What is the solution to (3 x 10^2) x (5 x 10^5) written in scientific notation? a: 1.5x10^8b: 16x10^8c: 1.5x10^7d: 15x10^7

Multiplying gives us 3 x 5 = 15

10^2 x 10^5 = 10^7

So we get 15 x 10^7.  However, we need to move the decimal point from 15.0 to 1.5:

1.5 x 10^8.  The answer is A.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
