Toby plans to build a BMX bicycle ramp with a height of 5 feet and an incline angle of 30°
Use a trigonometric function to determine the length on the ramp (the length of segment AC). In at least four sentences, explain why you chose your specific function and how it applies to the reference angle A. Be sure to include the key vocabulary words "sine", "ratio", "opposite side", "hypotenuse" and "angle measure" in your response. Describe each computational step in complete sentences.

so, converting firstly the mixed fractions to improper fractions and then "adding".

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
