Answer:
132 students
Step-by-step explanation:
100% means all of something, so 100% can also be written as 1.00
Since we need 55% of 240, we can multiply 240 by 0.55 and get 132.

Answer:
85
Step-by-step explanation:
Angle 1: 56
Angle 2: 39
56+39=95
A triangles angles add up to 180 degrees.
180-95=85
Angle 3:85
He would need to find the area of the room (area of the rectangle) by multiplying the length of the room by the width of the room.
