Answer:

9,065,738

Step-by-step explanation:

(3.8^3)^4

^ = exponents

(3.8^{3} )^{4}

Now lets do the parenthesis first

3.8 * 3.8 * 3.8 = 54.872

(54.872)^{4}

54.872 * 54.872 * 54.872 * 54.872 = 9,065,737.908494995

We can round that up to

9,065,738

Hope this helped!

One angle is eight times it’s supplement increased by 45 degrees. What is the measures of the two supplementary angles?
Nastasia [14]
Angle 1 = 8x + 45
Angle 2 = x

x + 8x  + 45 = 180
combine like terms

9x + 45 = 180
subtract 45 from both sides

9x = 135
divide both sides by 9 to isolate x

x = 15

Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees
