Answer 1

Answer:

Find the value of x in each of the given figures.

Step by step explanation :

a. .. Let the triangle be ABC

we have to find the value of A

so

ATTQ ( According to the question) we have ::

B = 25°

C = 105° + ___ = 180° ( adjacent angles)

C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)

The sum of all interior angles of a triangle is 180° .

so, A+B+C = 180°

A+ 25° + 75° = 180°

A+ 100° = 180°

A= 180° - 100°

A = 80°

therefore answer is 80°

b. .. Let the triangle be ABC.

we have to find the value of x

ATTQ , we have

A= 3x+2°

B=2x°

C = 152° + ___ = 180°

C= 180°- 152° = 28°

The sum of all interior angles of triangle is 180°

so, A+B+C = 180°

3x+2° + 2x° + 28° = 180°

first add the variables then numbers

5x° + 30° = 180°

5x° = 180° - 30°

5x ° = 150°

x° = 150° / 5

x = 30°

therefore answer is 30°
