Answer:
51. Don't completely know if it's correct though.
Step-by-step explanation:
I'd use sine, which is opposite side/hypotenuse. Here, I think the reference angle is x. The opposite side is 7, and the hypotenuse is 9. So...
sin(x) = [tex]\frac{7}{9}[/tex]
sin(x) = 0.7777
Next we use inverse sine.
sin⁻¹(0.7777) = approximately 51
The value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.
What is right angle triangle property?In a right angle triangle, the ratio of the opposite side to the hypotenuse side is equal to the sine angle between adjacent side and hypotenuse, side.
[tex]\sin\theta=\dfrac{b}{c}[/tex]
Here, (b) is the opposite side, (c) is the hypotenuse side and [tex]\theta[/tex] is the angle made between adjacent side and hypotenuse, side.
In the given figure, the hypotenuse side is 9 units long and opposite side is 7 units long.
The angle between adjacent side and hypotenuse is x degrees. Thus, by the right angle triangle property,
[tex]\sin x=\dfrac{7}{9}\\x=\sin^{-1}(0.778)\\x\approx51^o[/tex]
Hence, the value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.

A car requires 45 liters of petrol to travel a distance of 330 km.
1) the distance that the car can travel on 85 liters of petrol
2) the amount of petrol that the car owner has to pay to travel a distance of 990km if a liter of petrol costs $ 2.25.
Answers
Answer:
1) The car can travel 623.3 km with 85 liters of petrol.
2) The car owner has to pay $303.8.
Step-by-step explanation:
1) The distance traveled with 85 L of petrol can be found as follows:
[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]
Hence, the car can travel around 623 km with 85 liters of petrol.
2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:
[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]
Therefore, the car owner has to pay $303.8.

A. 4 cm
B. 3 cm
C. 8 cm
D. 7 cm
Answers
Answer:
8 is the answer
Step-by-step explanation:
the equation is r = C/2*3.14
2*3.14=6.28
Because your C is 50 you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.

Lisa is planning for a party. She receives quotes from two party planners. Choice A quotes $18 per guest, plus $100 for renting the party hall. Choice B quotes $15 per guest, plus $160 for renting the party hall. Which inequality represents the number of guests Lisa can invite, if choice A were to cost less than choice B?
Answers
Answer:
x<20
Step-by-step explanation:
Building linear functions for each situation, the inequality is:
[tex]18x + 100 < 15x + 160[/tex]
------------------
Choice A:
$18 per guest.$100 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_a(x) = 18x + 100[/tex]
Choice B:
$15 per guest.$160 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_b(x) = 15x + 160[/tex]
A cost less than B, thus, the inequality is:
[tex]C_a(x) < C_b(x)[/tex]
[tex]18x + 100 < 15x + 160[/tex]

Answer:
Step-by-step explanation:
sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{7}{14}[/tex]
= [tex]\frac{1}{2}[/tex]
= 0.5
cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{12.124}{14}[/tex]
= 0.866
tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{7}{12.124}[/tex]
= 0.577
Since, sinE = cosD
Therefore, sinE = 0.866
Since, cosE = sinD
Therefore, cosE = 0.5
Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{12.124}{7}[/tex]
= 1.732

The following two triangles are similar. Find x.
Answers
Answer and Step-by-step explanation:
Since we know that the triangles are similar, we can find the value of x. It appears that the lighter triangle is dilated to be smaller than the darker triangle.
So, We would divide 45 by 9 to find the scale factor.
45 divided by 9 is 5.
Now, we divide 25 by this to find x.
25 divided by 5 is 5.
x is equal to 5.

Step-by-step explanation:
1). 3x(2x - 2) = 3x(2x) + 3x(-2) [By distributive property]
2). x²(_ + 5x - 3) = (3)x² + x²(5x) + x²(-3)
3). _(x² - 3x + _) = x(x²) - (x)(-3x) + (x)(2)
4). (2x + 9)(x + 2) = 2x(x + 2) + 9(x + 2)
= 2x² + 4x + 9x + 18
= 2x² + 13x + 18
5). (z - 4)(2z + 1) = z(2z + 1) + (-4)(2z + 1)
= 2z² + z - 8z - 4
= 2z² - 7z - 4
