Answer:
Step-by-step explanation:
23). By applying triangle sum theorem in the given triangle,
(x + 83)° + (x + 48)° + 65° = 180°
2x + 196 = 180
2x = -16
x = -8
Measure of angle A = x + 48
= -8 + 48
= 40°
Therefore, Option A is the answer.
24). By triangle sum theorem,
(3x + 14)° + 90° + (4 + 3x)° = 180°
6x + 108 = 180
6x = 72
x = 12
Measure of angle A = (4 + 3x)
= 4 + 3(12)
= 40°
Therefore, Option A is the answer.

Answer: First equation: 3
Second equation: 6
Step-by-step explanation:
First equation:
The standard equation for a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the vertex of the circle and r is the radius
To find the radius, set r^2=9, since 9 is taking the place of r^2.
Square root each side, and only positive values are taken for a radius, so the radius is 3.
Second equation:
Using the same logic, we can find the radius for the second one.
The radius is r^2=36(remember that r^2 is taking place of 36)
Take the square root of both sides(only +), so the radius for the second problem is 6.

Ebony makes 2000 dollars. She spends 450
so 2000 - 450 = 1550
1550/2000 = 0.775
or .78
100 - 0.78 = 0.22
22% is your answer
hope this helps
