Question

Х815What is the value of x in the triangle?A. x = 7B. X= 12.7C. X= 17D. x= 23

Answer 1

A triangle of 90° angle

x = hypotenuse

a= 8

b = 15

Then apply Pithagoras rule

a^2 + b^2 = x^2

8^2 + 15^2 = x^2

64 + 225 = 289 = x^2

So then now find x, by radicals

√x^2 = √289

x= 17

THEN ANSWER IS

OPTION C)
