<1 and <2 are supplementary angles. They add up to 180 degrees.
92 and <2 are corresponding angles, they have the same measure.
So,<2 = 92 degrees
180-92= 88 degrees
<1= 88 degrees
I hope this helps!

Answer: A. 31%
Step-by-step explanation:
First you need to find the area within each circle. This can be found by using the formula: pi * r^2
The area of the circle with radius 8mm is 64 * pi. The area of the circle with radius 14mm is 196 * pi.
196 * pi = 615.75216
64 * pi = 201.06193
Now divide the larger area by the smaller area to get how many times larger the large area is than the small area.
615.75216 / 201.06913 = 3.06239
3.06239 rounds up to 3.1
Now we know the radius of 14mm has an area 3.1 times the area of 8mm. The area of an 8mm radius has 31% of the area of a 14mm radius.
Answer: 1. 2nd endpoint (24,-18) 2. 2nd endpoint: (-19,4)
Step-by-step explanation:
1.
= 7 x = 24
= -6 y= -18
2nd endpoint: (24,-18)
2.
= -10 x= -19
= 2 y= 4
It looks like you want to find the short leg (x) of a right triangle with long leg 15 and hypotenuse 18. The Pythagorean theorem gives the relationship between the sides of a right triangle.
18² = 15² + x²
324 = 225 + x²
x² = 324 - 225 = 99
x = √99 ≈ 9.9
The appropriate choice is ...
b) 9.9
