Find angles EFG pleaseee
Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = 180-(7x+18) because angles on a straight line add up to 180 degrees.

Angle EFG = 180-38-(180-(7x+18))=6x-10 (Angles in a triangle add up to 180)

180-38-\left(-7x+162\right)=6x-10

180-38+7x-162=6x-10

7x-20=6x-10

Add 20 to both sides:

7x-20+20=6x-10+20

7x=6x+10

Subtract 6x from both sides:

7x-6x=6x+10-6x

x=10

Angle EFG=6x-10=6(10)-10=60-10=50

AURORKA [14]

Answer:to find the equivalent positive angle of a negative angle, just add 360 to it until it becomes positive and is between 0 and 360 degrees. -110 + 360 = 250. 250 degree angle and -110 degree angle are coterminal
