Answer:
x = 10
Step-by-step explanation:
We know that is a right angle which is 90 degrees.
we know one angle is 30 degrees.
So take 90- 30 = 60
now we solve for 6x
6*10 = 60 and 60+30=90
x = 10
Answer:
The total percent decrease is 
Step-by-step explanation:
- We are given with a word problem
- We are asked to find the total percentage decrease
- We can do this in two steps
Step 1: Finding the two percentage decrease
Step 2: Finding their difference
Step 1 of 2
Let the decrease by a% be 100-a
Then b% decrease is

Step 2 of 2
The percentage difference between the two percentages is,

Since 100 is the total percent
is the percentage decrease.

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees
<h3>How to determine the central angle?</h3>
The given parameters are:
- Area = 75π cm^2
- Radius, r = 15 cm
The area is calculated using
Area = α/360 * πr^2
So, we have:
α/360 * π * 15^2 = 75π
Evaluate the exponent
α/360 * π * 225 = 75π
Divide both sides by 75π
α/360 * 3 = 1
Multiply
α/120 = 1
Multiply both sides by 120
α = 120
Hence, the measure of the central angle that forms the sector is 120 degrees
