Answer:
right triangle
Step-by-step explanation:
it wouldn't be obtuse because obtuse is if one of the angles is more than 90 degrees. Plus you can make a box at the bottom corner.
There are 6 faces to the prism:
2 each of (Length x Width): 2(4 x 4) = 2(16) = 32 m²
2 each of (Length x Heighth): 2(4 x 8) = 2(32) = 64 m²
2 each of (Width x Heighth): 2(4 x 8) = 2(32) = 64 m²
The sum of the faces is the Surface Area (S.A.)
32 m² + 64 m² + 64 m² = S.A.
160 m² = S.A.
Step-by-step explanation:
i+h=90
i+3h=210
so 2h=210-90=120
h=60
and i=90-60=30
so initial amount is $30 and hourly rate is $60
