Answer:
= 22.5°
= 67.5°
Step-by-step explanation:
Let’s create a system of equations for
and
.
Complementary angles are two angles that add up to 90°, so ![f+g=90](https://tex.z-dn.net/?f=f%2Bg%3D90)
Also,
is thrice of g: ![f=3g](https://tex.z-dn.net/?f=f%3D3g)
We can now substitute
in
for
.
![3g + g = 90\\\\4g = 90\\\\g=22.5](https://tex.z-dn.net/?f=3g%20%2B%20g%20%3D%2090%5C%5C%5C%5C4g%20%3D%2090%5C%5C%5C%5Cg%3D22.5)
Now, we can find
by substituting
into either equation.
![f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5](https://tex.z-dn.net/?f=f%20%2B%2022.5%20%3D%2090%5C%5C%5C%5Cf%20%3D%2090-22.5%5C%5C%5C%5Cf%20%3D%2067.5)
Hope this helped!
It’s b)2. Because if you simplify you divide by 3 ( because 6 is divisible by 3) and get 2/1 so your answer is 2
