Answer: 112.5 square units
Step-by-step explanation:
I think:
For the triangle:
1/2base(height) = 1/2(9)(7)= 31.5 sq. Units
For the small rectangle:
Length x width= 3 x 9 = 27 sq. Units
For the larger rectangle:
The length must be 16 - 7 - 3 = 6
So length x width = 6 x 9 = 54 sq units
Now add them together:
31.5 + 27 + 54 = 112.5 square units
A 90 degree clockwise rotation will leave the sides with the same length,
will leave the angles the same , it will only change the position of the triangle.
The rotated triangle will be congruent to the original triangle
17-2x that should be right
X=8.5 because angle B and angle D are congruent using alternate interior angles theorem. so you would find the measure of B by adding 50+45 to get 95, then subtract 95 from 180 to get 85 degrees for angle B. Now your equation is 10x=85 so if you divide 85/10 you get x=8.5! hope this helped :)
