Answer:
A = 467.99
Step-by-step explanation:
A = 25.12 (8 + √49 + 64)
A = 25.12 (8 + √113)
A = 25.12 (8 + 10.63)
A = 25.12 (18.63)
A = 467.99
Answer:
4 feet
Step-by-step explanation:
the 9 part of the ratio relates to 18 feet , then
18 ÷ 9 = 2 feet ← value of 1 part of the ratio , then
2 parts = 2 × 2 feet = 4 feet ← length on scale drawing
Answer:
21.38
Step-by-step explanation:
Find the diagram attached
In order to get PS, we need to get the length of QS first
According to triangle QRS;
QS =opposite
QR = 39(adjacent)
Using SOH CAH TOA
Tan theta = opp/adj
Tan 28 = QS/39
QS = 39tan28
QS = 39(0.5317)
QS = 20.74
Get PS
sin theta = QS/PS
sin 76 = 20.74/PS
PS = 20.74/sin76
PS = 20.74/0.9703
PS = 21.38
Hence the length of PS is 21.38
<u>0.917 = 0.9 + 0.01 + 0.007</u>
