Answer 1

m<B is the answer

all work is shown

Answer 2

B

Explanation:

we know that sum of all angles = 180°

A + B + C = 180°

(2x+7) + (4x-10) + ( 7x-25) = 180°

2x + 7 + 4x - 10 + 7x -25 = 180°

2x + 4x + 7x +7 -10 - 25 = 180°

13x - 28 = 180

13x = 180+ 28

13x = 208

x = 208/13

x = 16

∠B = (4x - 10) = 4(16) - 10

= 64 - 10 = 54

∠B = 54°
