Question

Find the missing side of the triangle​

Answer 1

Answer + explanation:

Answer: 40

To find a missing side length, use Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2 where a = x (in this case) b = 30 and c = 50

a^2 + 30^2 = 50^2

a^2 + 900 = 2500

a^2 = 2500 - 900

a^2 = 1600

square root 1600 = 40

the missing side length of the triangle is 40

Answer 2

x = 40

Explanation:

3-4-5 triangle scale factor by 10

Missing side is 4

4*10 = 40 | Multiply by 10 bc of scale factor

x = 40
