First, we find x using the given equation:
x = 4 / sin(53)
x = 5

We also know that:
Cos(∅) = base / hypotenuse
Therefore,
cos(53°) = y / 5

1) Find the values of 'a' and 'b' for the given parallelogram *

nataly862011 [7]

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

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

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4

Katy's favorite rides at the amusement park are the roller coasters and water slide. The wait time for the roller coaster is 25

ioda

Answer:

She went on the slide 8 times and on the roller coaster 4 times

Step-by-step explanation:

We convert each statements to a mathematical equation.

Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.

Mathematically, R + S = 12. ........(i)

Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.

To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.

Mathematically, 25R + 10S = 180 .......(ii)

Here we now have two equations that we can solve simultaneously.

From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:

25(12 - s) + 10s = 180

300 - 25s + 10s = 180

300 - 15s = 180

15s = 300 - 180

15s = 120

S = 120/15

S = 8

S = 8 , and R = 12 - S = 12 - 8 = 4

Geometry help quickly

lbvjy [14]

Answer:

RQ = 18

Step-by-step explanation:

KR is an angle bisector and divides the opposite side into segments that are proportional to the other two sides, that is

$\frac{KP}{KQ}$ = $\frac{PR}{RQ}$ , substitute values

$\frac{50}{45}$ = $\frac{38-x}{x}$ ( cross- multiply )

45(38 - x) = 50x ← distribute left side

1710 - 45x = 50x ( add 45x to both sides )

1710 = 95x ( divide both sides by 95 )

18 = x

That is RQ = 18

Fantom [35]

Answer:

The x-intercept is 2.

Step-by-step explanation:

$2 \sqrt[3]{x - 10} + 4 = 0$

$2 \sqrt[3]{x - 10} = - 4$

$\sqrt[3]{x - 10 } = - 2$

$x - 10 = - 8$

$x = 2$
