Correct diagram is J
Answer:
8
Step-by-step explanation:
When doing these types of problems, we convert the percent to a decimal. In this case,
40%=0.4
0.4*20=8
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!
<h3>Area of shape P = 12 square cm</h3>
Explanation:
Shape P is a triangle with the base of 4 units across the horizontal portion up top.
The height of the triangle is 6 units. Count the spaces down the middle of the triangle and you should get 6 spaces.
Area = base*height/2
Area = 4*6/2
Area = 24/2
Area = 12 square cm.
