Answer:
The cost for painting will be $212.
Step-by-step explanation:
I am painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall.
So, the total area to be painted = {2 × (20 + 30) × 10} + (20 × 30) = 1600 sq. ft.
Now, a gallon of paint covers 400 square feet and cost $53 per gallon.
So, the number of gallons of paint required will be 
gallons.
And the cost for painting will be $(4 × 53) = $212. (Answer)

Answer :
67.5 degrees
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
The sum of the measures of the angles of all triangles is 180 degrees.
Hence, the equation is
x + x + 45 = 180
Solve the equation for x
2x + 45 = 180
2x = 180 - 45
2x = 135
x = 67.5
Therefore, measure of other two angles are 67.5 degrees.
Answer: It's correct because it is the only one with an angle more than 180°
Step-by-step explanation:
D is a right angle, A is an acute angle, as well as B. So not only is C the only one with an obtuse angle and it also has the biggest angle out of the other two angles on the triangle, you can use process of elimination to figure it out as well. Hope this helps, have a good day! :-)
