Answer:
3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°
Step-by-step explanation:
Triangle g
180° = 80° + 3y + 2y
100° = 5y
y = 20°
Triangle h
y = 180° - 130°
y = 50°
180° = 4x + x + 50°
130° = 5x
x = 130 / 5
x = 26°
Since each side is r times the side of ABC, then 30*r+40*r+60*r is the perimeter, which equals 130r (by separating it into r*(30+40+60) using the distributive property)
0.7 is just 7 tenths which is literally 7/10.
Hey there! I'm happy to help!
is the same thing as 1/a². So, 
is 1/25. This is multiplied by 3² which is 9, so this is 9/25.
In the denominator, we have 
, which is 1/5. We multiply this by 3, which is 3/5.
So, we divide 9/25 by 3/5, giving us 3/5.
Now, we raise this to the power of -2, so we flip the numerator and denominator and then square both numbers, giving us 25/9.
Have a wonderful day! :D
