Answer 1

Answer:

x=-80°-65°+180°

x=35°

Answer 2

Answer:

sum of angles in a triangle is 180°

angle B=180-100

B=80°

since a straight line is 180° subract the angle from 180°

angle C= 180-115

C=65°

since a straight line angle is 180° subract the angle from 180°

angle A=x

angle A +angle B + angle C= 180°

80°+65°+X=180°

X=180-80-65

X=180-145

X=35°

hope you understand this
