In the given triangle, y = 32°.
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 9cm while the hypotenuse of the triangle measures 17cm. As we have the lengths of the opposite side and the hypotenuse side, we can calculate the sine of the value y.
sin y =
.
Step 2; Length of the opposite side = 9 cm.
Length of the hypotenuse side = 17 cm.
sin y =
=
= 0.5294.
We can multiply inverse sine on both sides to solve y.
y =
(0.5294) = 31.9657°.
Rounding this off to the nearest tenth we get, y = 32.0°.
Where is x and y ? i don’t see it in the equation
Answer: 900m
Explanation.
There are two ways you can solve to find the number of meters waved...I’ll show you how to do both.
Plan A:
1. Find the rate of meters weaves per hour by dividing 450 meters by 6 hours. The answer is 75 meters per hour.
2. Multiply the rate per hour (75) times 12 to find how many meters are weaved on 12 hours.
Plan A Answer: 900m
Plan B:
1. Set up a proportion like the one below:
2. Cross multiply and solve for x
Plan B answer: 900m
161.5 miles / 3.5 hrs = 46.143 mph
