Complementary angles equal 90 degrees. The ratio is 2:3.
2+3=5
90/5=18
2(18):3(18)
36 degrees, 54 degrees
Answer:

Step-by-step explanation:
First of all, let's rewrite the first one after dividing both sides by 2.

Now, let's pick one you want to eliminate.
<u>Eliminating x:</u> Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable

<u>Eliminating y:</u> Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable
