Answer:
mA = 69 degrees
Step-by-step explanation:
A complementary angle has a measure of 90 degrees.
(2x + 27) + (2x - 21) = 90
Simplify
4x + 6 = 90
-6
4x = 84
/4
x = 21
mA: 2(21) + 27 = 69
235+123 = 357

Answer:
3.49 radians
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We know s and r and need to calculate Ф.
From s = rФ we get Ф = central angle = s/r
Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
Answer:
1. blue
2. blue because I measured both lines with a ruler.
3. this one was harder to decide because when I look at the picture both lines look the same length but since I measured both lines with a ruler I realized that the blue line was longer that the red line.
Step-by-step explanation:
I actually measured both lines with a ruler and the blue line is just barely bigger that the red line
Answer:
f(3) = 7
Step-by-step explanation:
Using the recursive formula and f(1) = - 3 , then
f(2) = f(1) + 5 = - 3 + 5 = 2
f(3) = f(2) + 5 = 2 + 5 = 7
