Question

Help with math pls pls pls

Answer 1

∠B = 37°

Since the triangle is right then ∠B + ∠C = 90. hence

2x + 15 + 5x - 2 = 90 (simplify left side )

7x + 13 = 90 ( subtract 13 from both sides )

7x = 77 ( divide both sides by 7 )

x = 11, hence

∠B = (2 × 11 ) + 15 = 22 + 15 = 37°

Answer 2

<B + <C = 90

2x + 15 + 5x - 2 = 90

7x + 13 = 90

7x = 77

x = 11

<B = 2x + 15

<B = 2(11) + 15

<B = 22 + 15

<B = 37

Answer

37
