Answer:
A = 47° and B = 43°
Step-by-step explanation:
Express angle A in terms of angle B, that is
A = B + 4
Complementary angles sum to 90°, hence
A + B = 90, that is
B + 4 + B = 90
2B + 4 = 90 ( subtract 4 from both sides )
2B = 86 ( divide both sides by 2 )
B = 43
Hence
∠B = 43° and ∠A = B + 4 = 43 + 4 = 47°
Answer: Outside the circle
The radius is 6 so that's any point 3 units away from the center. -6 is five units away from -1 so it's outside the circle
a. Yes, the sum of the percentages is greater than 100 percent.
Answer: f(x)= 8
Step-by-step explanation:
First you would plug in F(3) into the equation
replace the x with a three
f(x)=2(3)+2
then multiply the 2 and 3 because when you see a number next to another number in parenthesis you multiply them
f(x)=6+2
Then lastly you would add the result of your multiplied numbers with the two which gives you f(x)=8.
<u>f(x)=8</u>
