Question

. Find the value of x.​

Answer 1

Answer:

80 degree

Step-by-step explanation:

As two sides are equal so its an isosceles triangle

In case of isosceles triangle base angles are equal

50 + 50 + x = 180 sum of angles in a triangle

X = 180 - 100

X =80

Answer 2

Answer:

80°

Step-by-step explanation:

Given that,

PQ=PR

<PRQ = 50°

Therefore, <PQR = 50° (Angles opposite to equal sides of an isosceles triangle are equal)

<PQR+<PRQ+<QPR =180° (Angle Sum Property of Triangle)

50°+50°+x = 180°

100°+x = 180°

x = 80°
