Answer:
x = 71
Step-by-step explanation:
Since the 2 legs are congruent ( both 21 ) then the triangle is isosceles.
Thus the base angles are congruent, then
x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71

Need help ASAP pls
Answers
Answer:
35Step-by-step explanation:
see attached image.
perimeter of trapezoid = sides (6 + 8 + 5 + 8 + 8)
= 35
the perimeter of trapezoid BMNC is 35
Given :
In triangle ABC shown below, L is the midpoint of BC, M is the midpoint of AB, and N is the midpoint of AC. If MN = 8, ML = 5, and NL = 6
By midpoint theorem ,
[tex]BC= 2 \cdot MN\\BC=2 \cdot 8\\BC=16[/tex]
M is the midpoint of AB, AB= 2 times NL
BM=NL
BM=6
N is the midpoint of AC
AC is 2 times of ML
NC=ML
NC=5
Perimeter of trapezoid is sum of all the sides
Perimeter of BMNC = BM+MN+NC+CB
Perimeter =[tex]6+8+5+16=35[/tex]

Answer:
a) ∆ABC ~ ∆EDC by AA similarity
b) ED/AB = 3/4
c) 15 cm
Step-by-step explanation:
a) Two angles in each triangle are the same, so the AA similarity postulate can be used to declare the ∆ABC ~ ∆EDC. (Each triangle includes a right angle and angle C.)
__
b) Corresponding sides are ED/AB, DC/BC, EC/AC. The ratio of corresponding sides is ED/BC = (12 cm)/(16 cm) = 3/4.
__
c) Using the ratios identified above, we have ...
DC/BC = 3/4 = x/(20 cm)
x = 3/4(20 cm)
x = 15 cm
[11 +{-18 divided by 9}]x2
HELP! Please and thanks
Answers
Answer:
7 is the answer.
Step-by-step explanation:
In equations like this, you would solve the numbers in the parenthesis first, and then gradually do: Multiplication -> Division -> addition -> subtraction.
Therefore, -18 / 9 is -2.
-2 * 2 would be -4,
11 + (-4) would be 7.

So with the expression 3 + 4 x 3 - 3 x 5 we know to multiply first. So let's multiply 4 x 3 and -3 x 5 first:
3 + 4 x 3 - 3 x 5
= 3 + 12 - 15
Then let's work out the rest of the expression!
3 + 12 - 15
= 15 - 15
= 0
Therefore we can determine that 3 + 4 x 3 - 3 x 5 = 0

If Cade shoots 318 free throw baskets in 4 hours, about how many can he shoot in 7 hours?
Answers
Answer:
556.5 baskets
Step-by-step explanation:
We can write a proportion to solve
318 baskets x baskets
----------------- = ----------------
4 hours 7 hours
Using cross products
318* 7 = 4 *x
2226 = 4x
Divide each side by 4
2226/4 = 4x/4
556.5 baskets
Answer:
556.5 baskets
Step-by-step explanation:
Write a proportion to solve
[tex]\frac{318}{4hours}[/tex] = [tex]\frac{x}{7 hours}[/tex]
Use the cross products
318 × 7 = 4 × [tex]x[/tex]
2226 = 4x
Divide both sides by 4
[tex]\frac{2226}{4x}[/tex] = [tex]\frac{4x}{4}[/tex]
556.5 baskets is your answer!

Find the range of the function for the domain {−3, 1, 4.5}.

A. {4, 2, −3.5}
B. {−2, 0, −5.5}
C. {−2, 2, −5.5}
D. {4, 0, −3.5}
Answers
Answer:
D. {4, 0, -3.5}
Step-by-step explanation:
domain (x) = {-3, 1, 4.5}
y= -x + 1
substituting domain/x-values into y= -x + 1
x= -3
y = -(-3) + 1
= 3+1
= 4
x= 1
y = -(1) + 1
= 0
x = 4.5
y = - (4.5) + 1
= -3.5
therefore, range ={4, 0, -3.5}
