Question

In a triangle, one angle is 15º more than another but 18° less than the third one. Find all the angles of the triangle.​

Answer 1

Answer:

Angles are 44° , 59° and 77°

Step-by-step explanation:

To Find : The measurements of three angles of the triangle

Let the first angle be X

then the second angle would be X - 15

and third would be X + 18

We know that sum all three sides of. a triangle is 180°

therefore,

X + X -15 + X +18 = 180

or, 3X + 3 = 180

3X = 177

X = 59

angles are X = 59°

X -15 = 44°

X +18 = 77°
