Question

find the value of x in each of the following figure​

Answer 1

Step-by-step explanation:

Let the angle be x

Therefore, other angle is 5x

We know now,

x + 5x = 90

6x = 90

x = 15

Therefore other angle is 15 (5) = 75°

Answer 2

Answer:

70

Step-by-step explanation:

As this is a isosceles triangle, the third angle will also be x.

=> 40° + x + x = 180° ( the sum of the sides of a triangle is equal to 180°)

=> 2x + x = 180° – 140°

=> x = 140°/2

=> x = 70°
