Question

if three angles of triangle are 2x°(x-5)° (2x+5)° then find the measure of each angel​

Answer 1

Answer:

Given the angles of the Triangle are

2x,3x,5x

Hence, 2x+3x+5x=180o (Interior angle sum is 180o)

⇒10x=180o⇒x=10180o=18o

So, the angles are

2x=2∗18o=36o3x=3∗18o=54o5x=5∗18o=90o

Answer 2

Step-by-step explanation:

We know that, sum of all angle of triangle is=180

Now,2x+x-5+2x+5=180

5x+10=180

5x=180-10

5x=170

X=170/5

X=34

First angle is 2x=2×34=68

Second angle is x-5=34-5=29

Third angle is 2x+5=2×34+5=73
