Answer:
47 m
Step-by-step explanation:
In the attached diagram, we find angle AKB to be ...
180° -55° -35° = 90°
Then the length of AK is ...
AK = AB·cos(35°)
and the height of the kite is ...
height = AK·sin(35°) = AB·sin(35°)cos(35°) = (AB/2)sin(2·35°)
height = 50·sin(70°) = 46.98
The height of the kite is about 47 meters.
Answer:
Concept:
In a function f(x), it represents a function in terms of x or for x. Therefore, to find the values in the function, substitute values within the parenthesis to solve.
Solve:
<u>Given information</u>
<u>Need to find</u>
<u>Substitute (x + 4) to the position of x</u>
<u>Distributive property on the numerator</u>
<u>Combine like terms</u>
Hope this helps!! :)

It's a parallelogram so if one angle is 90 degrees they all will be because of transverse angles and all that good stuff.
So we're given the diagonal of a rectangle and one side and we're asked to find the other. The diagonal of a rectangle is the hypotenuse of the right triangle whose legs are the sides of the rectangle. So this is a Pythagorean Theorem question in disguise:
Answer: 140 cm
I don't recall seeing this Pythagorean Triple before.
