Square b area = 144 ÷ 2
area = 72 in squared
area in feet = 6 ft squared
Answer:

Step-by-step explanation:
From the complete question, we have:
Length D to be perpendicular to side AC
So, the area of the triangle is:

Since:
Length D is perpendicular to side AC
Then:


So:

Cos (3π/4) can be written as,
cos (π-π/4) = -cosπ/4 = -1/√2
similarly sin3π/4=sin(π-π/4) = sin π/4 = 1/√2
The key idea here is that
speed of plane in wind = (speed of plane in air) + (speed of wind)
Let
be the speed of the plane in still air, and
the wind speed. A tailwind blows in the same direction as the plane, so for the first leg of the trip, we have

For the return trip, the wind would blow in the opposite direction:

Solve this system and you'll find
and
.
Answer:
X = 24
Step-by-step explanation:
Just apply H² = B² + P²
(26)² = (10)² + P²
676 = 100 = P²
676 - 100 = P²
P² = 576
P = √576
P = 24
P = X
