Step-by-step explanation:
complementary angles means that both of them together = 90
13y +12 + 20y + 12 = 90
add all y together and numbers together
33y + 24 = 90
solve for y
33y= 66. y= 2
now let's get the measurements of the angles
13(2) + 12= 38
20(2) + 12= 52
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
Answer:
Step-by-step explanation:
X = 0
Everything gets canceled out
Mark brainliest please :))
(A) because it is reflecting over the x-axis.
<span>(5 2/3+8 1/4)+9 3/4=n+18
</span><span>5 2/3+8 1/4+9 3/4=n+18
</span>5 2/3 + 18 = n + 18 | - 18
5 2/3 = n
