Question

plz help me to gind answer ​

Answer 1

Answer:

x = 50°

Step-by-step explanation:

<CBA + <B = 180° (Linear pair)

<CBA + 115° = 180°

<CBA = 180° - 115° = 65°

<CBA = 65°

In triangle ACB,

Since BC = AC (given)

triangle ACB is an isosceles triangle.

Therefore, <CBA = <CAB = 65°

In triangle ACB,

<CAB + <CBA + < ACB = 180° (Angle Sum Property)

65 + 65 + x = 180

130 + x = 180

x = 180 - 130 = 50

=> x = 50°
