Answer:
NC = 7.7
C = 63.6°
T = 26.4°
Step-by-step explanation:
✔️Apply pythagorean theorem to find the length of NC:
NC = √(17.2² - 15.4²) = √58.68
NC ≈ 7.7
✔️Apply trigonometric function to find Angle T:
Reference angle = T
Hypotenuse = 17.2
Adjacent length = 15.4
Apply CAH, thus:
T ≈ 26.4°
✔️C = 180 - (90 + 26.4) (sum of triangle)
C = 63.6°

Answer: Choice A) -32</h3>
A loss of 8 yards is represented as -8
Multiply this by 4 to get -8*4 = -32
<u><em>Answer:</em></u>
35 square units
<u><em>Explanation:</em></u>
<u>Area of parallelogram is calculated as follows:</u>
Area = base * height square units
<u>In the given question, we have:</u>
base = 5 units
height = 7 units
<u>Substitute with the givens in the above equation to get the area:</u>
Area of parallelogram = 5 * 7 = 35 square units
Hope this helps :)
Answer:
Step-by-step explanation:
we are given
- Amplitude:7
- Period:9π
- Phrase shift:¼
remember that,
where A is the Amplitude
B is the Period
C is the Phase shift
D is the vertical shift
note that, since D isn't given we'll take it 0
altogether substitute:
hence,
our equation is
and we are done!
Answer:
10
Step-by-step explanation:
area=√3/4×a^2
100√3 = √3×a^2
a^2 = 100
a=10
side = 10
