Answer:

7.5\cdot 10^9 g

Step-by-step explanation:

In this problem, we are told that the mass of 1 grain of sand is:

m=1\cdot 10^1 g

The total mass of N grains of sand will be therefore

M=Nm

where

N is the number of grains of sand

M is the total mass

Here we have a number of grains of sand equal to

N=7.5\cdot 10^8

Therefore, the total mass of the grains of sand is:

M=(7.5\cdot 10^8)(1\cdot 10^1 g)=7.5\cdot 10^9 g

  • We know, sum of all angles of a triangle is 180°.
  • Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6
