Answer: y=31.97°
Explanation: We can use trig ratios to find y and they are SohCahToa.
We can use Sin y, because when y is the reference angle, the 9 cm side is the opposite and the 17cm is always the hypotenuse.
We must take the inverse of Sin (9/17) to get about 31.9657, which we can round to 31.97°.
The square root of 4 is 2
Answer:
-18
Step-by-step explanation:
A is at -30. AE = 12
So, E is -30+12 = -18
Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
To write this value simply write the first part of the value before the decimal point
Which is 34
Then since it says 12 hundredths, make sure to place them after the decimal place.
0.12 = 12 hundredths
34.12 would be the answer.
