Answer:
30 ft²
Step-by-step explanation:
Area of trapezium = 1/2 (a + b)h
a = 6 ft , b = 9 ft , h = 4 ft
Area = 1/2 (6 + 9) 4
= 30 ft²
7 hours is 28 quarter hours. 50 is closer to 45 than 00 so it is. 75 hours. total is 28.75
The angle of 25° is the complement of the angle of 65° and the angle of 65° is the complement of the angle of 25°.
Answer:

Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is
.
Because all the angles of a triangle sum to
, we have that
.
We combine like terms on the left side to get
.
We subtract
on both sides to get
.
So,
and we're done!
We can't really factor it, because it's already simplified. We only need to add...


Have a nice day! :)
