Answer:
30.
Step-by-step explanation:
The total degree of a triangle is 180.
They give you 60.
The center line coming down creates a 90 degree angle.
So 60+90=150.
180-150=30.
So the top angle is 30 degrees on both sides.

1. Find the area of the two sides (length x height) x 2 sides
2. Find the area of the adjacent sides (width x height) x 2 sides
3. Find the area of ends (length x width) x 2 ends
4. add the three areas together to find the surface area
1.925
Explaining:to write 77/40 as a decimal you have to divide the numerator by the denominator of the fraction.We divide now 77 by 40 what we write down as 77/40 and we get 1.925
4/6 can be one because the denominator is 6
