Answer:
1. 3
2. 1
3. 9
4. 30
Step-by-step explanation:
1. 2*(18/12) = 3
2. 3*(5/15) = 1
3. 4*(45/20) = 9
4. 21*(10/7) = 30
It’s the first one because it has 7 rows and 7 columns which show that it is 7 times 7 or 7^2.
The law of sines can be used to find the missing side lengths.
... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247
... PS = sin(75°)/sin(45°)·10 ≈ 13.660
Then the perimeter is
... perimeter = RS + RP + PS
... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units
Answer:
93.5
Step-by-step explanation:
55 multiply
<u>1.7</u>
385 ≥ add 385 and 550
