Question

Can someone please help with this question

Answer 1

X = 7.2

Explanation:

Hello

For the triangle of right side, using Pytagoras:

(2.5)^2 + b^2 = 6^2

6.25 + b^2 = 36

b^2 = 36 - 6.25

b^2 = 29.75

b = 5.45

Now we can to find X using again Pytagoras:

3^2 + (5.45)^2 = x^2

9 + 29.75 = x^2

38.75 = x^2

X = 7.2
