Answer:
144°
Step-by-step explanation:
First, find the area of the circle, with the formula A = 
r²
Plug in 10 as the radius, and solve
A = r²
A = (10²)
A = 100
Using this, create a proportion that relates the area of the sector to the degree measure of the arc.
Let x represent the degree measure of the arc of the sector:
= 
Cross multiply and solve for x:
100x = 14400
x = 144
So, the degree measure of the sector arc is 144°
Answer:
45
Step-by-step explanation:
OK, first we turn the variables into into the actual values:
The equation will look like this:
(2)5 + (-5)(-7)
Now its easier to solve! Lets solve (2)5!
2 * 5 = 10
The equation looks like:
10 + (-5)(-7)
We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!
-5 * -7 = 35
Lets finish the rest:
10 + 35 = 45.
Hope this is correct and have a nice day!

Answer:
5/13
Step-by-step explanation:
Find the diagram to the question attached
Given the following considering angle A
Hypotenuse = 13 = AB
Opposite = 5 (side facing the angle A) = BC
Adjacent = 12
According to SOH CAH TOA;
Sin theta = opposite/hypotenuse
Sin(a) = BC/AB
Sin(a) = 5/13
Hence the value of sin(a) is 5/13
