Answer:

<A = 45

<B = 110

<C = 25

Step-by-step explanation:

The sum of the angles of a triangle add to 180

x+ x+65 +25 = 180

Combine like terms

2x+90 = 180

Subtract 90

2x+90-90 = 180-90

2x = 90

Divide by 2

2x/2 = 90/2

x = 45

<A = x = 45

<B = x+65 = 45+65 = 110

<C = 25

∠A = 45 °

∠B = 110 °

∠C = 25 °

Step-by-step explanation:

We know that sum of all angles of triangle is 180°.

x + x + 65 ° + 25 ° = 180 °

combine like terms

2 x + 90 ° = 180 °

Subtract 90 ° from each side

2 x + 90 ° - 90 ° = 180 ° - 90 °

2x = 90 °

Divide 90 ° by 2.

x = 90 ° / 2

x = 45 °

Therefore,

∠A= x = 45 °

∠B = x + 65 ° = 45 ° + 65 ° = 110 °

∠C = 25 °
