Answer:
x = 8.6 cm
y = 12.3 cm.
Step-by-step explanation:
sin 35 = x / 15
x = 15 sin 35 = 8.6 cm.
cos 35 = y / 15
y = 15 cos 35 = 12.3 cm.
Hey there! I'm happy to help!
First we need to find the slope, which is the incline of the line. To do this, you divide the difference of the y values by the difference of the the x values.
3-8=-5
-2-0=-2
-5/-2=5/2
To find the y-intercept, you want to find where the line hits the y-axis. Well, the point (0,8) tells us that the y-intercept is 8. The y-axis is where x=0, so our y-intercept is 8.
Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
So....
y=5/2x+8.
Have a wonderful day! :D
Two parallel strings of 12 and 20 cm are drawn in a circle. If the distance
between them it is 4 cm; How big is the diameter?
Answer:

Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that

Multiply both sides by 5


Multiply both sides by Area{circle}


Substitute the areas of sector and circle with their respective formulas;


So, we have

Divide both sides by 


Multiply both sides by 360


Divide both sides by 5




Hence, the central angle is 216 degrees
Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is

Simplify it:
