For #1. 3x + x +7 = 180 degrees
4x + 7 = 180
4x = 173
so x = 43.25
For #2. 2x + 5 = 110 degrees
2x = 105
so x = 52.5
For #3. 1 and 3, 2 and 4, 5 and 8, 6 and 7.
Answer:

Step-by-step explanation:
Point slope form is: 

We are given the slope of
and the point of (8,4).
Replace 'm' with -5/6, 'x1' with 8, and 'y1' with 4.

I do not see any options that match this, but the boxed equation should the correct answer.

Answer: 7.71 feet.
Step-by-step explanation: <em>The formula for finding the circumference of a circle is
π × d + d.</em>
The diameter is 3 feet. Substitute this into the equation:
π × 3 + 3.
Solve -
3.14 × 3 = 9.42
of 9.42 = 4.71
4.71+3 = 7.71
Round -
The answer is already rounded.
Hope this helped!~
That 's easy!!! (x-h) ²+(x-k) ²=r²
(h, k) is the coordinate of centra
r is radius
and(x-h) ²+(x-k) ²=r² is written in standard form, which u can directly get the value of center and radius
so for ur question center is (7 and -4)
radius is 7
Answer:
PN
Step-by-step explanation:
A secant is a line that intersects with a circle's outer-rim and continues to travel outside the circle.
