A the other ones really don’t make sense
Answer:
(x^2 + 2x - 21) sq units
Step-by-step explanation:
Area of the shaded region = Area of the larger rectangle - Area of smaller rectangle
Area of the larger region = x(x+2)
Area of the larger region =x^2 + 2x
Area of the smaller rectangle = 3 * 7
Area of the smaller rectangle = 21 sq. units
Area of the shaded region = x^2 + 2x - 21
Hence the required expression is (x^2 + 2x - 21) sq units
Answer:
Below.
Step-by-step explanation:
Angle 1 = (3/(3+4+5) * 180 = 3/12 * 180
= 45 degrees.
Angle 2 = 4/12 * 180 = 60 degrees.
Angle 3 = 5/12 * 180 = 75 degrees.
Find the inside angle B of the smaller triangle using the base (4) and height (6)
smaller part of B = arctan(4/6) = 33.69 degrees
full B = 90 degrees - smaller B gives you the other part of B for the left hand side
so 90 - 33.69 = 56.31
now AD = 6 x tan(56.31) = 9 feet
answer is G
