Question

If ac =bc then find the value of x ​

Answer 1

Answer:

AB= BC

then angleA= angle C

angleA+angleB+angleC = 180⁰

A+B+40 = 180⁰

2A = 180-40

=140

A. =. 140/2

70⁰

x = 180-angleC

180- 70

= 110⁰

I hope you understand

Answer 2

Answer: 80

Step-by-step explanation:

If ac=bc

So, the triangle is equilateral

By using property,

The triangle having same opposite sides also have same opposite angles.

so, angle B = angle A = 40

Now, by using exterior angle property

angle A + angle B = x

40+40=x

x=80
