We have been given that in ΔBCD, the measure of ∠D=90°, the measure of ∠C=42°, and CD = 7.5 feet. We are asked to find the length of DB to nearest tenth of foot.
First of all, we will draw a right triangle using our given information.
We can see from the attachment that DB is opposite side to angle C and CD is adjacent side to angle.
We know that tangent relates opposite side of right triangle to adjacent side of right triangle.
Therefore, the length of DB is approximately 6.8 feet.

Hello,
The slope of the 1st side is 2 (y=2x)
The slope of the 2 nd side is -1/2 (y=-x/2+5/2)
The two sides are perpendicular so we can find the vertex.
y=2x (1)
2y+x=5
If we substitue y by is value in (1)
2(2x)+x=5==>5x=5
==>x=1 and y=2*1=2
Vertex is (1,2)
In order to find the rectangle we must know an other vertex.
