Factor the polynomial.
Answer:
482.5 ft^2.
Step-by-step explanation:
The figure can be regarded as a rectangle with a triangle cut out of one corner.
The base of the triangle = 25-20 = 5 in and the height = 20 - 13 = 7 in.
The required area = area of rectangle - area of triangle
= 25*20 - 1/2 * 5 * 7
= 500 - 17.5
= 482.5 ft^2
Answer:
117
Step-by-step explanation:
Sum of all the angles of a triangle is 180
Let the third angle be 'x'
41 + 22 + x = 180
63 + x = 180
x = 180 - 63
x = 117
