Answer:
C. 69 (nice)
Step-by-step explanation:
Sine: Opposite side over hypotenuse
Cosine: Adjacent side over hypotenuse
Tangent: Opposite side over adjacent side
Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.
cos(O)=5/14
O=arcsin(5/14)≈69.0752
The answer is 69.

Answers
Answer:
The answer is below
Step-by-step explanation:
PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm
The breadth of PQRS = a. Hence:
Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab
but Area of PQRS = 84 cm²
9a + ab = 84 (1)
In rectangle PXYS, length = QR = a cm, breadth = YS = b cm
Hence area of PXYS = length * breadth = (a)(b) = ab
But Area of PXYS = 21 cm²
ab = 21 (2)
substitute ab = 21 in equation 1:
9a + 21 = 84
9a = 84 - 21
9a = 63
a = 7 cm
ab = 21
7b = 21
b = 3 cm
Therefore a = 7cm, b = 3 cm
If 35 people going to the movie bought popcorn and that was 20% of all the people at the movie how many people were at the movie
Answers
Answer:
Im pretty sure it would be 700 but im most likely wrong.
If 35 people is 20% of all people, we can assume that 35 is 1/5 of all the people at the movie since 20% is 1/5 of 100%
All we have to do is multiple 35 by five.
I can prove my answer by dividing 175 by 5 which would give me 20% of 175

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)
m<L = (7x + 9)° is an inscribed angle
m(KM) = 46° is its intercepted arc
Therefore:
7x + 9 = ½(46)
Multiply both sides by 2
2(7x + 9) = 46
14x + 18 = 46
14x + 18 - 18 = 46 - 18
14x = 28
14x/14 = 28/14

Whats the slope of the line?
Answers
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.
