It is supposed to be right angle(90 degree)
Answer:
43.5√3 sq. units
Step-by-step explanation:
Base 1 of trapezoid is 10.
Base 2 of trapezoid is 16 + 3 = 19
The height = 3√3 (To get the height you had to multiply the number 3 from the bottom base of the trapezoid by the square root of three)
Now plug these numbers into the trapezoid formula: A = 1/2(3√3)(10 + 19)
Simplify to get: 43.5√3 sq. units
Hope this helps you understand! P.S. I helped someone else out on this problem, so I just copied and pasted my answer from the previous brainly question onto here. :) So, it's still my own work.
