Question

the angles of triangle are (x+10)°, (x+40)° and (2x+30)° find the measure of all angles​

Answer 1

Explanation:

sum of all angles of triangle is 180

x+10+x+40+2x+30=180

4x+80=180

4x=100

x=25

by substitution of value of x

angles = 35,65,80

Answer 2

Answer:

According to Linear pair angle property

$(x + 10) + (x + 40) + (2x + 30) = 180 \\ 4x + 80 = 180 \\ 4x = 180 - 80 \\ x = \frac{100}{4} \\ x = 25$
