Answer:
1. x=74
2. x=86
Step-by-step explanation:
1. the sum of interior angles in a triangle is 180 degrees
81 + 25 + x = 180
106 + x = 180
x = 74
2. once again the sum of interior angles in a triangle is 180 degrees so add up the terms and set them equal to 180
x + x-35 + 43 = 180
add up like terms (x and x, -35 and 43)
2x +8 = 180
2x = 172
x = 86
I know the answere it is c

Answer:
22320
Step-by-step explanation:
simple interest= p (deposit) × r (rate) × t (time)
=1550×7.2×2
=22320
4:5 = x : 15
let x be blue marbles
4(15) = 5x
x = 12
therefore 12 blue marbles
