Answer:
Here's how to solve.
Step-by-step explanation:
10 to the 4th power= 10,000
So it would be 2.25*10,000
22,500 would be your answer.
Z = 99°
~ It is equivalent to the angle across from it.
X = 4
~ 99+7x+53=180 (add similar terms)
152+7x=180 (subtract 152 from both sides)
7x=28 (divide by 7)
x=4
