Question

find the value of x in the triangle shown below​

Answer 1

Answer:

x=55°

Step-by-step explanation:

Suppose it is triangle ABC

A at x°

B at 70°

C at third angle

AB=BC=5 cm

Angles opposite to equal sides are equal

angle C=angle A

angle C=x°

angle A+angle B+angle C=180° (Angle Sum Property)

x°+70°+x°=180°

2x=180°-70°

2x=110°

x=110°/2

x=55°
