Question

Please answer all 3 questions I will give brainliest if I can if ur right!

Answer 1

Answer:

1. 30 ft

2. sqrt(2164) yd

3: 12 cm

Step-by-step explanation:

For all three questions I'll be using the Pythagorean Theorem which states that a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the base and height

Question 1:

40^2 + d^2 = 50^2

1600 + d^2 = 2500

d^2 = 900

d = 30

Question 2:

42^2 + 20^2 = c^2

2,164 = c^2

c = sqrt(2164)

Question 3:

5^2 + a^2 = 13^2

25 + a^2 = 169

a^2 = 144

a = 12
