Answer:
The value of x = 7
Step-by-step explanation:
Given the right triangle
- We know that the sum of angles of a triangle is 180°.
so
Right angle + α + β = 180°
90° + 4x+7 + 8x-1 = 180
Group like terms

Add similar elements: :4x+8x=12x



Divide both sides by 12


Therefore, the value of x = 7

Answer:
b 125
Step-by-step explanation:
