Step-by-step explanation:
Third angle = 180 - (40 + 60)
= 180 - 100

Use the Pythagorean theorem:
Answer:
7/3
Step-by-step explanation
4y+8=29-5y
First you are going to subtract 8 from both sides of the equation.
4y=21-5y
Next you are going to add 5y to each side of the equation.
9y=21
Now write it as a fraction,
9/21
Last but not least simplify.
3/7
