m∠A = 40°

m∠B = 70°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

x + 49 + x + 79 + 70 = 180

2x + 198 = 180

2x = 180 - 198

    = -18

x = -18 ÷ 2

x = -9

m∠A = x + 49

        = (-9) + 49

m∠A = 40°

m∠B = x + 79

        = (-9) + 79

m∠B = 70°

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
