Answer:
60 degrees
Step-by-step explanation:
A triangle adds up to 180 degrees. 180 divided by 3 is 60. The answer is 60 degrees.
Answer:
B, D, E and F are correct.
Step-by-step explanation:
B - PQ is parallel to RS. This is true as opposite sides of a rhombus are parallel.
D - PQR is supplementary to QPS. Two angles are supplementary when they add up to 180 degrees.
E - PR is perpendicular to QS. This is true because the diagonals of a rhombus bisect each other at right angles.
F - PS is parallel to QR. This is true as opposite sides of a rhombus are parallel.
answer y = -222 when x = 74
Step-by-step explanation:
84 / -252 = 74 / y
84y = (-252)(74)
84y = -18,648
y = -18,648 / 84
y = - 222
answer y = -222 when x = 74
