All the angles inside a triangle add up to 180°.
(2x + 15) + (5x + 5) + x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
the question is asking what angle B is,
B = 2(20) + 15
B = 40 + 15
B = 55°
Answer:
a. 2*-2*3=-12
b. -2*3*5 = -30
c. (-2)^2+2*5= 14
d. 2*-2+3*3-5*5= -20
e. -2(3-5) = 4
f. 3*5-(-2)*5+(-2)*3 = 19
