Find the measure of the missing angle *

Mathematics
1 answer:
sergeinik [125]3 years ago
8 0

Answer:

≈ 49.9° and ≈ 71.0°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin? = \frac{opposite}{hypotenuse} = \frac{13}{17} , then

? = sin^{-1} (\frac{13}{17} ) ≈ 49.9° ( to the nearest tenth )

----------------------------------------------------------------

Using the cosine ratio in the right triangle

cos? = \frac{adjacent}{hypotenuse} = \frac{14}{43} , then

? = cos^{-1} (\frac{14}{43} ) ≈ 71.0° ( to the nearest tenth )

Simplify:<br> 8(v+w) - 7(v+2w)
Liula [17]
First you need to distribute. when you do this you get (8v+8w)-(7v+14w) then you get like terms together, but don't forget that everything in (7v+14w) is negative. when you group like terms together you get (8v-7v)+(8w-14w) simplify and you get v-6w

What are the length of each side of a quadrilateral when the perimeter is 33 and the sides are:
solong [7]
Answer: 
A = 6 
So 
Side A = 6 
Side B = 11 
Side C = 3 
Side D = 13

Explanation: 
To solve perimeter of a quadrilateral, you use this formula: 
side A + side B + side C + side D = total perimeter.

If the four sides are A, A + 5, A – 3, and 2A + 1 then you need to solve for A.

Write out an algebraic formula with these values:
A + (A + 5) + (A – 3) + (2A + 1) = P 
You also know that the total perimeter is 33, so :
A + (A + 5) + (A – 3) + (2A + 1) = 33 
You can add all the A values together to combine like terms like this:
5A + 5 – 3 + 1 = 33 
Solve fore A:
5A + 3 = 33 
5A = 33 – 3 
5A = 30 
A = 30 ÷ 5 
A = 6 

Check your answer: 
A + (A + 5) + (A – 3) + (2A + 1) = 33 
(6) + ((6) + 5) + ((6) – 3) + (2(6) + 1) = 33 
(6) + (11) + (3) + (13) = 33 
17 + 16 = 33 
33 = 33

Which of the following equations is of a parabola with a vertex at (1, -2)?
Lapatulllka [165]

Answer:

y = (x-1)^2 - 2

Step-by-step explanation:

The parabola vertex point is always (h, k) in y = (x-h)^2 + k

All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
