Question

If y° and 48° are a pair of complementary angles then find y°

Answer 1

❄ Hi there,

the sum of complementary angles is always 90°.

If we know one of these angles, we can set up an equation –

`\triangleright\sf{y+48=90}`

and then solve for y...

`\triangleright \ \sf{y=42}`

That's it!

Answer 2

y = 42 and/or x = 36

Explanation:

y + 48 = 90
y = 42 (subtracted 48 from 90)

3x + 2x = 180 (angles are linear pairs)
5x = 180 (combine like terms)
x = 36 (divided by 5 on both sides)

I didn't know which question you needed help with, I hope this makes sense :)
