Question

if angle of a triangle are 3 Y - 5 degree 2y + 25 degree and 5 y- 50 degree find the value of Y and get answers please

Answer 1

Given that angle of triangle are 3 Y - 5 degree 2y + 25 degree and 5 y- 50 degree.

We know that sum of all the angles of triangle is 180 degree so if we add given angles then we get equation:

3y-5+2y+25+5y-50=180

combine like terms

10y-30=180

10y=180+30

10y=210

y=210/10

y=21

Hence final answer is y=21.

and the angles are

3y-5=3*21-5=63-5=58

2y+25=2*21+25=42+25=67

5y-50=5*21-50=105-50=55
