Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = , cos30° =
, then
sin30°= =
=
( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = =
=
( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
The equation can be used to find the missing leg in the triangle .
A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
It is given that a right triangle has a side length of 16 meters and a hypotenuse of 20 meters.
From a Pythagoras theorem
Thus, the equation can be used to find the missing leg in the triangle .
