Your answer is z=423/7.
Hoped I helped!
Answer:
Step-by-step explanation:
12) looking at the right angle triangle,
x = hypotenuse
y = adjacent side
Opposite side = 4
To determine x, we would apply
the sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = 4/x
x = 4/sin30 = 4/0.5
x = 8
To determine y, we would apply
the Cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos 30 = y/8
y = 8Cos30 = 8 × 0.866
y = 6.93
14) looking at the right angle triangle,
hypotenuse = 22
y = opposite side
x = adjacent side
To determine y, we would apply
the sine trigonometric ratio.
Therefore,
Sin 45 = y/22
y = 22Sin45 = 22 × 0.7071
y = 15.6
x = y = 15.6 because the triangle is an isosceles triangle.
If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile
X/4 + x/5 = 1
5x/20 + 4x/20=1
9x/20 =1
9x = 20
x = 2.22 hours
