Question

Find the value of X in the following cases ?​

Answer 1

Answer:

c. 40°+50°= 90°

= 180° - 90°

= 90°

Total degree of a straight angle is 180°

x+90° = 180°

x = 180° - 90°

x = 90°

So the x value is 90°

d. 60° + 60° = 120°

= 180° - 120°

= 60°

total degree of a straight angle is 180°

So,

x + 60° = 180°

x = 180° - 60°

x = 120°

So the value of x is 120°

e. 110° + 20° = 130°

= 180° - 130°

= 50°

total degree of a straight angle is 180°

So,

x + 50° = 180°

x = 180° - 50°

x = 130°

So the value of x is 130°

Answer 2

Answer:

(C )angle c is 90°

Step-by-step explanation:

A + B + C = 180°

C = 180° - 50° + 40°

angle C = 90°
