Answer:
Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>
<em />
Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
It has three lines of symmetry.
Answer:
If light passes in an angle to a surface with a particular refractive index it refracts. This change in direction is due to a change in velocity. As light , for example, travels from air through water, it slows down, allowing it to continue travelling at a different angle or direction.
Step-by-step explanation:
Yes it because any positive number is greater a negative number
Answer:y =

-
Explanation:The slope-intercept form of an equation has the following formula:y = mx + c
where:
m is the slope
c is the y-intercept
The given is:17x + 4y = -14
To put this in slope-intercept form,we will need to isolate the y as follows:17x + 4y = -14
4y = -17x - 14
y = (-17/4)x - (14/4)
y =

-

where:
m is the slope = -17/4
c is the y-intercept = -7/2
Hope this helps :)
