5.
Find the value of x
(a) 60°
(b) 110°
c) 50°
(d) 180

Answer 1

Step-by-step explanation:

c is the write answer

the sum of the angle of the triangle is 180

Answer 2

The value of x will be 120 degrees.

Given:

a triangle as shown in the image above

the 2 angles of the triangle are 50° and 70°

x is an exterior angle

To Find:

we need to find the value of x in the triangle

Solution:

now, since we know that the value of the external angle of a triangle is equal to the sum of opposite interior angles of that triangle.

thus, the value of x can be calculated as-

x = 50 + 70

x = 120 degrees

Thus, the value of x comes out to be 120 degrees.
