The sum of the measures of angles xand y is 120°. The measure of the angle x is 12 less than the measure of the angle y. Find x

Troyanec [42]

Answer:
x = 54°
y = 66°

Step-by-step explanation:

x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)

M + t + w = 19
t = 2m
w = t - 6....w = 2m - 6

m + (2m) + (2m - 6) = 19
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <===Monday

t = 2m
t = 2(5)
t = 10 ... Tuesday

w = 2m - 6
w = 2(5) - 6
w = 10 - 6
w = 4 .... Wednesday
