Question

in a triangle angleA is 25 degree more than angleB and angleB is 20degree less than angleC what is the measure of all the angles​

Answer 1

Answer:

Let the value of angle c be x.

Therefore

Angle B = x- 20

Angle A = x - 20 +25 = x + 5

By angle sum property of triangle

X + x - 20 + x + 5 = 180

3x - 15 = 180

3x= 195

X = 195 / 3

X = 65

Angle C = 65

Angle B = 65 - 20 = 45

Angle A = 65 + 5 = 70

The value of all angle are 45, 65 and 70.

Answer 2

Answer:

let C= x

B=20x

A=45x

A+B+C=66x

66x= 360

x=360/66=5.45

C=x=5.45

B=20x=5.45*20=109

A=45x=5.45*45=245.25
