I can use the angle and the length of JH to find the length of IJ.
To do this, I look at the relationship IJ and JH have to the 52 degree angle. JH is opposite to angle I, and IJ is adjacent to angle I. Because the two side lengths are opposite and adjacent, I use the tangent function to solve this.
Tangent of an angle = the length of the opposite side / the length of the adjacent side. This is just another way to say tan(x)=opposite/adjacent
Now I can fill in what I know...
tan(52)=4.2/x
Now, I want to isolate x.
tan(52) = 4.2/x
x(tan(52))=4.2
x=4.2/tan(52)
Now I put 4.2/tan(52) into a calculator and get x = 3.3 ft
Hope this helps!
#2 is C because you are looking at the Y-axis and i don't know if you needed help for #3 but if you did I can't see the question.
Answer:
105 is the part.
Step-by-step explanation:
175 is the whole
60% is the percent
x is the part
175 * 0.60 = 105
Answer:
its 38
Step-by-step explanation:
use a calculator like i did :)
