Question

Find the measure of each angle...? Stuck!

Answer 1

8)
The sum of angles of a triangle is 180º
Therefore:
x+x+98=180
2x=180-98
2x=82
x=82/2
x=41

Answer:
m∠E=41º
m∠F=41º

10)
The sum of angles of a triangle is 180º
Therefore:
3x+4x+5x=180º
12x=180
x=180/12
x=15

3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: 
m∠G=75º
m∠H=60º
m∠J=45º
