In triangle efg the measure of angle e is four times the measure if angle f. the measure of angle g is 18 degrees less than the measure of angle e. what is the measure of each angle?

Step-by-step explanation:

In our triangle, angles E + F + G = 180 degrees.  If angle E is 4 times the measure of F, and G is 18 less than E, then

F is x,

E is 4x, and

G is 4x - 18

Add these all together and set the sum equal to 180:

x + 4x + 4x - 18 = 180

Combining like terms:

9x - 18 = 180 and

9x = 196 so

x = 22

That means that

F = 22,

E = 4(22) = 88 and

G = 4(22) - 18 = 88 - 18 = 70

Since 22 + 88 + 70 do in fact equal 180 you can be fairly certain that your answer is correct! (It is correct...trust me!)
