Question

Find the measure of all the angles. ​

Answer 1

Answer:

∠A=72°

∠B=35°

∠C=63°

Step-by-step explanation:WE NEED TO USE ANGLE SUM PROPERTY FOR THIS SUM.

SUM OF ALL THE ANGLES IN A TRIANGLE =180°

SO ACCORDING TO THE PROBLEM

∠A+∠B+∠C=180°

(2x+2)+(x)+(2x-7)=180°

if we add all x then it is 5X

if we add thenumbers then it is -5

5x-5=180°

5x=180°-5

5x=175°

x=175°/5

x=35°

so if we substitute x value we get

∠A=2x+2=2(35)+2=70+2=72°

∠B=x=35°

∠C=2x-7=2(35)-7=70-7=63°

hope this is helpful to you
