Answer 1

Answer:

AB=5.6

Step-by-step explanation:

Answer 2

Answer:

AB ≈ 5.6 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

Calculate the value of x

Answers

Answer:

x = 55

Step-by-step explanation:

x + (2x+15) = 180

3x + 15 = 180

3x = 165

x = 55

Answer:

55°

Step-by-step explanation:

since angles in a straight line add up to 180°

x+2x+15=180°

3x+15=180°

3x=180-15

3x=165

divide by 3 on both sides

x=55°

The ratio of the measures of the sides of a triangle is 21:8:14. The perimeter is 215 feet, find the length of each side

Answers

14 - 30.1
8 - 17.2

What is the length of the shortest side if the perimeter of the rectangle is 56 inches?

Answers

Answer: Length of Shortest Side = 12 inches

Step-by-step explanation: Length of Shortest Side = L = 3x

Length of Longest Side = W = 5x-4

Condition:

2L+2W = Perimeter

2(3x)+2(5x-4) = 56

6x+10x-8 = 56

16x-8 = 56

Adding 8 to both sides

16x = 56+8

16x = 64

Dividing both sides by 14

=> x = 4

Now,

Length of the Shortest Side = L = 3(4) = 12 inches

Length of the Longest Side = W = 5(4)-4 = 16 inches

Kermit flipped a coin 20 times. The coin landed on tails six times. Which best describes what would likely happen if Kermit flipped the coin another 80 times?

Answers

Answer:

24 of those times would be tails.

Step-by-step explanation:

Because if you flip it 20 times and it lands on tails 6 times, you just have to add 20+20 6+6 so then it's 40 flips and 12 tails. 60 times and 18 tails 8p times and 24 tails.

Isaac’s family took a cab to a concert. The bill came to a total of $43.50. The family wants to tip the driver at least 20%. Which tip amounts would be sufficient? Select all that apply.

$7
$8
$9
$10
$11

Answers

Answer:

The option d is the correct answer

to find a percentage of something we were taught this method

%% x
—— • ——
100 total price

you then want to multiply the total price by the percentage and then divide by 100

so in this case

20 x
—— • ——
100 $43.50

20•43.50=870

870/100= 8.7

so i believe 9,10,11 would all be correct.
hope this helps!
