Question

In a triangle abc , angle a is x , angle b is 2x + 2 , angle c is 2x - 7. find x

Answer 1

Answer:

ok

Step-by-step explanation:

In a triangle ABC :

angle A + angle B + angle C = 180

--------------(angle sum property of triangle)

• angle C - angle B = 9

y - (3x-2) = 9

y = 9+(3x-2)

y = 7+3x

•x + (3x-2) + y = 180

x + (3x-2) + (7+3x) = 180

x + 3x + 3x -2+7 = 180

7x = 175

x = 25°

• y = 7 + 3×25

y = 82°

The respective angles of the triangle ABC are ;

Angle A = x = 25°

Angle B = 3x-2 = 73°

Angle C = y = 82°

Answer 2

Hi , the answer to your question is below,

Answer:

x=37

Step-by-step explanation:

By angle sum property in a triangle,

x+2x+2+2x-7=180

5x-5=180

5x=185

x=37
