The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm
Hope this helps :)

Question:
which point is 8 units away from ( 7, 5 ) ?
Choices:
A : (0,-3 )B (15,13) C ( 7, -3 ) D ( 1, 5 )
Solution:
(7, 5) and (7, 3) have the same x-coordinate, 7.
They are both on a vertical line that passes through point (7, 0).
(7, 5) is 5 units above the x-axis.
(7, -3) is 3 units below the x-axis.
5 + 3 = 8
(7, 5) and (7, 3) are 8 units apart.
Answer: C ( 7, -3 )
Answer:
20
65
95
Step-by-step explanation:
Remark
You have to use a constant to get the ratio so that it will produce angles that will add up to 180. Let that constant = x
Equation
4x + 13x + 19x = 180
Solution
Add the like terms on the left.
36x = 180
Divide both sides by 36
36x/36 = 180 /36
Combine
x = 5
Answer
4x = 20
13x = 65
<u>19x = 95</u>
Total = 180
