Question

In ∆XYZ, If angle X=2x+10^ , angle Y=3x-10^ °, angle Z=5x-30^ , find the measure Of angles of ∆XYZ.​

Answer 1

Answer:

X = 52 Y= 53 Z= 75

Step-by-step explanation:

addition of all angles of a triangle is 180

therefore, X+ Y+ Z= 180

2x + 10 + 3x - 10 + 5x -30= 180

10x = 210

x = 21

therefore, X = 2x + 10 = 52

Y = 3x - 10 = 53

Z =5x -30= 75
