Answer:

Step-by-step explanation:
The window consists of a large square and 4 smaller triangles on the outside. The side length of this square is marked as 10, and therefore the area of this square is
.
The area of a triangle is given by
. Since the problem states that the overlapping squares are congruent, both legs of the triangle will be
and intersect at a
angle.
Thus, the sum of all four triangles is
.
Therefore, the area of the window is:

Answer:
these are the step to follow so A=bh
Step-by-step explanation: A=1/2bh A=bh A=1/2 (b=b)h this is an example so you can follow how i did this
Answer:
ac is parallel to df because it doesn't intersect with each other
The leg rule is hypotenuse/leg and the altitude rule is side 1/altitude=altitude/side 2
Answer:
B) x=12
Step-by-step explanation:
x+22+4x+2= 5x+24
5x+24=84
5x=60
x=12
