Answer:
82.5
Step-by-step explanation:
The formula for the area of triangle is 1/2 B * H
1/2 of the base is 7.5
multiply that by 11
and you get
82.5
The prallelogram whose adjacent sides are equal and one vertex angle is 90 degrees is a square.
The value of angle 1 is 90 degrees as the diagonal of the square intersect at 90 degrees.

The value of y is 23.
The diagonal of the square bisect the vertex angle hence the angle of 3x is 45 degrees.

Thus, the value of x is 15 degrees.
The value of 12z is 45 degrees.

Thus, the required value of z is 3.75 degrees.
-4x+7x-14
3x-14>-18
3x>-4
X>-4/3
Answer:
Well 3^17-3^15+3^13 equals 116,385,579
Now divide that by 73
So 116,385,579 ÷ 73
That equals 1,594,323
Hope this helps
