Answer:
Step-by-step explanation:
Based off of what we do know, if we can find length DB we can use the pythagorous theorem (I will be assigning the variable z)
First equation is for triangle ABD
Second is for BCD
And the last one is for ACD
Substitute 
and 
As discovered before
48 is the answer because when it’s a negative number it subtracts
The dimension of a square is altered so that one dimension Is increased by 7 feet While the other is decreased by 2 feet The area of the resulting rectangleIs 90 feet with a 2 up top what is the original squareArea of the square I will tell you the answer right now it is going to beA= 64 feet with the two up top
7 minus f in algebraic expression= 7-f is the answer
Traiangle ABE = triangle CBD this is wrote right
bc. to angle A corespond angle C
and to angle B corespond angle B
and to angle E corespond angle D
so and than you check this posted image these coresponding angles are congruent angles what mean that these two triangles are congruent
