Answer:
x = 10°; Angle A = 84°
Step-by-step explanation:
Angle A + Angle B = 180
5x + 34 + 2x + 76 = 180
7x + 110 = 180
7x = 70
x = 10
Angle A: 5(10) + 34 = 50 + 34 = 84°
Answer:
84
Step-by-step explanation:
Because the two lines are parallel, the angles are supplementary. This means they will add up to 180 degrees.
So all you have to do is add the measures of the two angles to get 180.
<u>5x+34</u>+<u>2x+76</u>=180
(simplify)
7x+110=180
7x=70
x=10
Now all you have to do is plug this into the equation for <A
5(10)+34=?
50+34=?
84=84

Answer:
39
Step-by-step explanation:
x-3y=9
x-y=29
subtract
-2y=-20
y=10
x-10=29
x=39
Answer:
Step-by-step explanation:
The square indicates that the total angle is 90 degrees so
d+59=90
d=90-59
d=31 degrees
