Answer:
B 16/y = y/25
C x/16 = 9/x
Step-by-step explanation:
Start with 1/5x – 2/3y = 30. Let y = 15: (<span>1/5)x – (2/3)(15) = 30
Then (1/5)x - 10 = 30, and (1/5)x = 40, and so x = 200 (answer)</span>
ZCBE and ZDEB are same-side interior angles.
is the correct answer
Answer:
22 degrees to the nearest degree.
Step-by-step explanation:
Use the Cosine Rule
3^2 = 5^2 + 7^2 - 2*5*7*cos T
9 = 74 - 70 cos T
cos T = (74-9)/ 70
cos T = 65/70
m < T = 21.8 degrees.
