here is what i found also you could of looked it up
Step-by-step explanation:
(x,y)→(x+4,y)
if indeed r || s, that will only occur if those two corresponding angles of 1 and 2 are equal to each other, namely ∡1 = ∡2, or 60 - 2x = 70 - 4x.
you need to change 1 3/8 into a mixed fraction, which would be 11/8, but with this fraction, you need to do the reciprocal, which would be 8/11 multiplied by 3/4. You can cross simplify 8 and 4 changing the fractions being multiplied to 2/11 and 3/1. Then you need to multiply straight across, which would get an answer of 6/11.
Answer:
225 x a^4
Step-by-step explanation:
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
