Question

B) In a triangle if ZA = 45°, ZB = 65°. Find the measure of ZC.​

Answer 1

Answer:

70°

Step-by-step explanation:

let zc be x

sum of triangle=180°

za+zb+zc=180°

45°+65°+x=180°

110°+x=180°

x=180°-110°

x=70°

so,zc is 70°

Answer 2

Answer:

70

Step-by-step explanation:

because sum of interior angles of triangle is 180

so,

ZA + ZB + ZC = 180

45 + 65 + ZC = 180

110 + ZC =180

ZC = 180 - 110

ZC = 70
