Answer:
i. a = 7
ii. b = 7
iii. c = 14
Step-by-step explanation:
1. In a parallelogram, the pair of opposite sides are equal, thus;
6a + 10 = 8a -4
4 + 10 = 8a - 6a
14 = 2a
Divide both sides by 2,
a = 7
2. <SPQ + <PSR =
(18b - 11) + (9b + 2) =
18b + 9b + 2 -11 =
27b -9 =
27b = +
27b =
Divide both sides by 27,
b = 7
Therefore,
c = a + b
= 7 + 7
= 14
c = 14
