Answer:
Step-by-step explanation:
s:m = 7:5
s = 7x, m = 5x
(7x+10):(5x+10) = 9:7
(7x+10)/(5x+10) = 9/7
7(7x+10) = 9(5x+10)
49x+70 = 45x+90
x = 5
s = 7x = 35, m = 5x = 25
Sonu is 35, Monu is 25
Answer:
∠ 1 = 20°, ∠ 2 = 160°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, that is sum to 180°
x - 12 + 5x = 180 , that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = x - 12 = 32 - 12 = 20°
∠ 2 = 5x = 5 × 32 = 160°
