Answer:
Explanation:
11) looking at the right angle triangle,
Hypotenuse = y
Adjacent side = 13
Opposite side = x
To determine y, we would apply
the cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos 45 = 13/y
y = 13/Cos 45 = 13/0.7071
y = 18.38
Also, x = 13 because the triangle is an isosceles right angle triangle.
12) looking at the right angle triangle,
Hypotenuse = x
Adjacent side = y
Opposite side = 21
To determine x, we would apply
the sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 60 = 21/x
x = 21/Cos 60 = 21/0.5
x = 42
To determine y, we would apply
the tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan 60 = 21/y
y = 21/tan60 = 21/1.7321
y = 12.12
