Answer:

angle BAC = 57.84°

Step-by-step explanation:

To find angle BAC given AB=6cm    BC= 13 cm   and ACB=23°

we will follow the steps below;

we can use the sine formula to solve the problem given

[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]

from the question given;

A = ?

C = 23°

c=AB  = 6 cm

a=BC = 13 cm

substitute the values into the formula above

[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]

[tex]\frac{sin A}{13}[/tex]  =  [tex]\frac{sin 23}{6}[/tex]

cross -multiply

6 sinA =  13 sin23°

sin A = 13 sin23°  /  6

sin A = 0.84658

take the [tex]sin^{-1}[/tex] of both-side

[tex]sin^{-1}[/tex] sin A =  [tex]sin^{-1}[/tex] (0.84658)

on the left-hand side of the equation [tex]sin^{-1}[/tex] will cancel-out sin leaving us with just A

A =  [tex]sin^{-1}[/tex] (0.84658)

A ≈ 57.84°

angle BAC = 57.84°

Answer:

The alternative interior angles theorem.

Step-by-step explanation:

The alternate interior angles theorem states that, when two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

Answer:

Improper fraction = 10/3 cups

Mixed fraction = 3 1/3 cups

Step-by-step explanation:

Given;

Sam uses 2/3 cup of sugar to make cookies

Rate = 2/3 cup per batch

To make 5 batches, he would need;

Amount = number of batches × rate per batch

Amount = 5 batches × 2/3 cups per batch

Amount of sugar he would need = 10/3 or 3 1/3 cups

Answer:

9 × (1 × 4) = (9 × 1) × 4

Step-by-step explanation:

Number 3 because the associative property states that it doesn't matter how you add / multiply something in sets.

9 × (1 × 4) = (9 × 1) × 4 shows 9 × 1 × 4 in 2 ways with 2 sets.

Answer:

9 × (1 × 4) = (9 × 1) × 4 is the answer because it means you can group in any combination

Step-by-step explanation:

9 × (1 × 4) = (9 × 1) × 4

Answer:

The answer is B

Answer:

x = 9

Step-by-step explanation:

→Looking at the angles, you can see that a right angle is formed. This means that there must be another right angle (90 degrees) formed with the numbers. You can set up the equation, like so:

3x + 6 + 57 = 90

→Add like terms (6 and 57):

3x + 63 = 90

→Subtract 63 from both sides:

3x = 27

→Divide both sides by 3:

x = 9

Answer:

x=9

Step-by-step explanation:

a right angle is 90 degrees

90-57= 33

33-6=27

27/3 = 9

Answer:

468

Step-by-step explanation:

5+3/ 4 =2

2*234=468

Answer:

Step-by-step explanation:

They are dividing the denominator by 3. So, the answer is 2/1 or basically the number 2.

For example,

27/3 = 9

9/3 = 3

The last math shows how I got the answer.

Hope this helps!

Answer:

2

Step-by-step explanation:

Answer:

1, 3, 9, 27, 81, is a geometric sequence.

Step-by-step explanation:

A geometric sequence is basically a sequence of numbers that's multiplied by or divided one specific set number each time.

0, 2, 6, 12, 72, does not have a set number it is multiplied or divided by each time.

4, 9, 14, 19, 24, adds 5 each time, it doesn't multiply

Answer:

D - 1, 3, 9, 27, 81, . . .

Step-by-step explanation:

Answer:

y = 4x + 16 (fourth answer choice)

Step-by-step explanation:

From the given equation we can immediately discern that the slope of these lines is 4 (as they are parallel).

Starting with the slope-intercept formula y = mx + b, we get:

32 = 4(4) + b, or 16 = b, or y = 4x + 16

Answer & Step-by-step explanation:

In order to solve this problem, we are going to have to divide. Since the triangles are similar, then that means that we are going to have to find the ratio between the sides which will also be our scale factor.

We can divide 75 by 15 since they are corresponding sides. Once we find the ratio between the sides, then we can conclude that the scale factor would be that number.

75 / 15 = 5

So, the scale factor of XYZ to UVW is 5.

The scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.

The ratio that we get when you divide corresponding side lengths of similar figures is called the scale factor.

According to the given question.

We have a two triangles Xyz and UVW. And both the triangles are similar to each other.

In triangle Xyz we have

[tex]Xy = 60[/tex]

[tex]yz = 75[/tex]

and

[tex]zX = 90[/tex]

Also, in triangle UVW we have

[tex]UV = 12[/tex]

[tex]VW = 15[/tex]

and, [tex]WU = 18[/tex]

Therefore, the scale factor of Xyz to UVW is given by

[tex]\frac{Xy}{UV} =\frac{yz}{VW} =\frac{zX}{WU}[/tex]

⇒ [tex]\frac{60}{12} =\frac{75}{15} =\frac{90}{18} =5[/tex]

Hence, the scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.

Thus option B is correct.

Answer:

Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.

Step-by-step explanation:

An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.
