Answer:
Just wanted to say someone already gave you an answer of 62.7° in this question when you asked it before, they also gave a pretty good explanation!
Answer:
$67.70
Step-by-step explanation:
Multiply 51.20 by 0.32 then add that to 51.20
Answer:
360 cm^2.
Step-by-step explanation:
Area of the base = 10*10 = 100 cm^2.
We find the slant height of the sides using Pythagoras:
h = sqrt ( 12^2 + 5^2)
h = sqrt 169
h = 13.
Area of the triangular sides = 4 * 1/2 * 10* 13
= 260 cm^2
So the total surface area = 100 + 260
= 360 cm^2.
