Answer: The climb angle is 14°
Step-by-step explanation:
We can create a rectangle triangle, where the velocity of the plane is the hypotenuse, the horiontal component (1000 ft by unit of time) is a cathetus and the vertical component is (250ft by unit of time).
We want to find the angle that is adjacent to the horizontal component, so we can use the relationship.
Tan(angle) = opposite cathetus/adjacent cathetus
Tan(angle) = 250/1000 = 1/4
Angle = Atan(1/4) = 14°

The area of the window is 182 square inches.
Option: B.
<u>Step-by-step explanation:</u>
From the given data, we are given with the length of the upper side of the trapezoid, the right side's bottom excluded the length upper side's length and height of the trapezoid.
Area of an isosceles trapezoid =
( a+b) h.
where a is the length of upper side of the trapezoid, b is the length of lower side of the trapezoid and h is the height of the trapezoid.
a= 12 inches.
h= 13 inches.
We are given only with the right side's length of base excluding the length of upper side.
So we have to calculate b= left side + upper side+ right side.
b= 2+12+2.
b= 16 inches.
Area of an isosceles trapezoid =
(12+16)(13).
=
(28)(13).
= 14(13).
= 182 square inches.
∴ Area of the window= 182 square inches.
