Answer:
x=130
Step-by-step explanation:
triangle=180
180-34-96=50
line=180
180-50=130
Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
=
( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y =
≈ 61 ( to the nearest whole number )
Answer:
4 13/18
Step-by-step explanation:
This problem is equivalent to 17/6 times 5/3, which comes out to 85/18, or 4 13/18.
It's the first choice. If you multiply the first equation by 3, your y term is a +12, and if you multiply the second equation by 4, your y term is a -12. When you add them the y terms cancel each other out.
