Question

In a triangle the second angle is
5 more than the 1st angle. And the
third angle is 3 times of the first angle.
Find measures of each of the angle.​

Answer 1

Answer:

third angle's measurement. Their sum is 180 degrees; thus you can add the three expressions to get an equation that ...

Answer 2

Answer:

let the angles be x

so second angle will be 5+x and ,

third angle will be 3x

According To Problem

we know the the sum of all the angles of a triangle is 180°

x + 5+x + 3x = 180°

5x+5= 180°

5x = 180°-5

5x = 175°

x = 175°/5

x = 35°

now x = 35 then first angle will be 35°

second angle will be 5+x that is 5+35°= 40°

third angle will be 3x = 3×35° = 105°

so angles are 35°,40° and 105°
