Answer:
71º is measure of angle A
19º is measure of angle B
Step-by-step explanation:
complementary angles are angles that equal to 90º
so let's add the terms (from angles A & B) and set them equal to 90º
3x+2 + x-4 = 90
4x -2 = 90
add 2 to both sides to get rid of the 2 on the left side and isolate our similar terms
4x = 92
divide both sides by 4
x=23
We're not done though, we must plug in our x value to Angle A terms and Angle B terms.
(3(23) + 2)º = measure of Angle A (solve for both of them)
(23-4)º = = measure of Angle B
3(23) + 2 =
3(23) = 69 (add the 2)
71º is measure of angle A
23-4 = 19º
19º is measure of angle B
double-check
71+19 = 90º
It works
Answer:
X= -8
Step-by-step explanation:
4-12=-8
You must reverse the problem so that you are solving for x, rather than 4.
Answer:
Step-by-step explanation:
if you modify the parent function to go <u>up and down</u>
for example parent function is y=|x| to go <u>down</u> 3 you do y=|x|-3
if you modify the parent function to go <u>left and right</u>
for example parent function is y=|x| to go <u>right </u>3 you do y=|x-3|
a.goes down 3, and 2 to the right
y=|x-2|-3
b. 3 down and 1 to the left
y=(x+1)²-3
c. 5 up and 2 to the right
d. 1 up and 5 to the right
