They're complementary.
Complementary angles are a pair of two angles that add up to a sum of 90 degrees
Supplementary angles add up to 180 degrees
63 + 27 = 90
Answer:
{y = x/4 + 2, 3 y = -(3 x)/4 - 6}
Step-by-step explanation:
21/35= 3/5 this is the lowest fraction
Answer:
d. 22
Step-by-step explanation:
(PQ + QR) × QR = (TS + SR) × SR => two secants intersecting theorem
PQ = ?
QR = 2
TS = 8
SR = 4
Plug in the values
(PQ + 2) × 2 = (8 + 4) × 4
2PQ + 4 = 12 × 4
2PQ + 4 = 48
2PQ + 4 - 4 = 48 - 4
2PQ = 44
2PQ/2 = 44/2
PQ = 22
