Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
8v + 8b = 240
4v + b = 54
------
Modify:
8v + 8b = 240
8v + 2b = 108
------
Subtract and solve for "b":
6b = 132
b = 22 (# of students in each bus)
-----
Solve for "v":
4v + b = 54
4v + 22 = 54
4v = 32
v = 8 (# of students in each van)
Answer:
18 units^2
Step-by-step explanation:
There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.
