Let x represent the time spent for valleyball
Then swimming will be 2x
x + 2x = 4.5
3x = 4.5
x = 4.5/3
x = 1.5
Time spent on valleyball: 1 1/2 hours
Time spent on swimming: 3 hours
Answer:
32 units²
Step-by-step explanation:
this shape is a trapezoid with a height of 4 and bases that are 4 and 12 units in length
formula is: 1/2(height) x (sum of bases)
A = 1/2(4)(4 + 12)
A = 2(16)
A = 32
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
