What is the surface area of the triangular pyramid shown?round to the nearest tenth.

57.6 cm/mm/m/in/ft squared

Step-by-step explanation:

You will need to answer the each triangle separately which you have to use the formula 1/2*b*h

5.2*1/2(6) = 15.6

4*1/2(6) = 12

5*1/2(6) = 15*2 (2 sides)

total = 57.6 cm/mm/m/in/ft squared

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
