Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos X = 
= 
= 
, then
∠ X = 
( ) ≈ 44° ( to the nearest degree ) → A
324
Because you multiply 9 by 36
Answer:
x=16.75 y=4.5
Step-by-step explanation:
first turn the first trapezoid sideways so the side that says 8 matches with the side that says 10. This is the proportion. 8:10. The bottom of the first trapezoid says x+2. This matches with the side that says 15. Because the side that says 15 is on the bigger trapezoid, multiply by ten. Then multiply the other trapezoid by 8. We get an equation that looks like. 8x+16=150 Simplify and 8x=134 divide and we get x=16.75. Do the same for the side with y. 8y-24=50. 8y=36 y=4.5. There you have it.
Answer:
125
Step-by-step explanation:
Answer:
Part B: 4 is the constant
Part C: y = 4x
Step-by-step explanation:
y = kx
k = constant
y = 4x
4 is the constant
