In right triangle ABC, A=15°, C=37, and angle C is the right angle. Solve the triangle. Round to the nearest tenth, if necessaar

Mice21 [21]

Answer:

180 degrees

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees. Since angle C is 90 degrees and angle A is 15 degrees Then,

A+B+C=180

15+90+B=180

B=180-90-15

B=75 degrees

Using the sine law,

a/sinA = b/sinB = c/sinC

where a, b, and c are the sides of the triangle,

So,

a/sin15 = 37/sin90

and

b/sin75 = 37/sin90

Simplifying, and solving for a and b, the measure of each side is

a= 9.58 units

b=35.74 units

I hope this helped. I am sorry if you get this wrong.

line passes through the point (-3,-4) and its y-intercept is (o, -9). What is the equation of the line that is parallel to the f

12345 [234]

Answer:

$y=-\frac{5}{3}x-2$

Step-by-step explanation:

The first line has a slope of -5/3 found using the points in the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1} =\frac{-9--4}{0--3}=\frac{-9+4}{0+3}=\frac{-5}{3}$

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form $y-y_1=m(x-x_1)$ .

$y--7=-\frac{5}{3}(x-3)\\y+7 = -\frac{5}{3}(x-3)\\y=-\frac{5}{3}x + 5 -7\\y=-\frac{5}{3}x-2$

Mr Oneill bought cheese, turkey slices and wheat rolls for $55. The ratio of the amount of money spent on cheese to the amount o

astra-53 [7]

Answer:

Mr. O'neill buy 33 turkey slices.

Step-by-step explanation:

Firstly let us denote amount of money spent on Cheese by the symbol C.

amount of money spent on Turkey by the symbol T.

amount of money spent on Wheat by the symbol W.

Now we are the ratio of amount of money spent on cheese to the amount of money spent on turkey slices as 2:3 ;

We can represent this as $\frac{C}{T}$ = $\frac{2}{3}$

The ratio of the amount of money spent on cheese to the amount of money spent on wheat rolls is 6:5 ;

We can represent this as $\frac{C}{W}$ = $\frac{6}{5}$

Now we will make C also 6 in the first ratio to represent similarity in ratios i.e. $\frac{C}{T}$ = $\frac{2 * 3}{3 * 3}$ = $\frac{6}{9}$

So, the ratio of amount of money spent on cheese to the amount of money spent on turkey slices to the amount of money spent on wheat rolls is represented by 6 : 9 : 5.

To find the amount of money spent on turkey slices = $\frac{9}{6+9+5} * $55$ = $24.75

Since cost of each turkey slice cost = $ 0.75

Therefore, Cost of each turkey slice * Number of turkey slices = Total amount of money spent on turkey slices

$0.75 * Number of turkey slices = $24.75

Therefore, Number of turkey slices that Mr. O'neill buy = $24.75/$0.75

= 33 slices.

pochemuha

Answer:

2.5

Step-by-step explanation: i just solved it and it was correct. 300-250=50 50 divided by 20 is 2.5. you divide it by 20 because you have to isolate h in 20h by itself. and to do that you divide 20h by 20
