Answer:
138 degrees
Step-by-step explanation:
I'm assuming you meant measurement of angle 1 = 42 degrees.
If d//m, then angles 1,4,5, and 8 all have to have the same angle measurement. Likewise, angles 2,3,6, and 7 all have to have the same angle measurement.
So, because we know the angle measurement of angle 1, we can use that to calculate angle 2. Because angle 1 + angle 2 = 180 degrees, we can just do 180 - angle 1 to calculate the measurement of angle 2, which would be 138 degrees. Because angle 2 and angle 7 have to be the same measurement in order to have d//m, angle 7 must be 138 degrees.
Answer:
add ans subtract like normal
Step-by-step explanation:
Given:
Angle A is 4 degrees greater than the measure of Angle B. Both angles are complementary
Complementary angles have a sum of 90°
Angle A = x + 4° ; Angle B = x
x + 4° + x = 90°
2x = 90° - 4°
2x = 86°
x = 86° ÷ 2
x = 43° ANGLE B.
Angle A = x + 4° ⇒ 43° + 4 = 47°
Given:
Angle D is 5 times the measure of Angle E. These angles are supplementary. This means that their sum is 180°
Angle D = 5x ; Angle E = x
5x + x = 180°
6x = 180°
x = 180° ÷ 6
x = 30° Angle E.
Angle D = 5x = 5(30) = 150°
