Find the height of the triangle10 points!
5 months ago
Q:
find the height of the triangle10 points!
Accepted Solution
A:
By the 6 trigonometric ratios in a right triangle
(sine, cosine, tangent, cotangent, secant, cosecant)
we have the following:
[tex]\displaystyle{ sin20^o= \frac{opposite \ side}{hypothenuse}= \frac{x}{10} [/tex]
So, [tex]x=10\cdot sin20^o[/tex]
sin20° must be given, or can be found using a calculator:
Using the calculator of our pc: Calculator- view:Scientific- press 20 then sin button, we find : sin20°=0.342
[tex]x=10\cdot sin20^o=10\cdot0.342=3.42[/tex]
Answer: A)3.4
