15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
Answer:
540 ft^2.
Step-by-step explanation:
The area of the trapezoid = h/2 (10 + 18) = 14h.
By Pythagoras the height h = √(5^2 - 4^2) = 3.
So the area of the 2 trapezoidal bases = 2 * 14*3
= 84 ft^2.
Now we calculate the area of the four lateral rectangular sides:
= 10*12 + 18*12 + 2*5*12
= 456 ft^2.
Total area = 456 + 54
= 540 ft^2.
Answer:
95
Step-by-step explanation:
you first find out the angles mn and mt.
Since ns and ms are the same, we know ms is 35 degrees.
mt is 50, so we subtract 50 and 35 from 180, which is the degree of m.
so the answer is 95 degrees.
