Molly flies a kite that is attached to a string that is 100 meters long. The angle of elevation of the kite is 36 degrees. If she is holding the string 1 meter above the ground, how high is the kite?
COuld you guys describe to me, or make it someone if possible how the diagram of the right angle triangle would look like. I don't understand the 1m part, it throws me off.

Draw a right angled triangle, ABC, right angled at C.
Vertical height from hand is BC
Horizontal is AC
sin A = BC /100
sin 36° x 100 = BC
BC = 58.8 m (to 1 decimal place)
Height of kite = 59.8 m

don't let the 1 extra meter get you. Just add it after you figure out how high the kite is from where it is being held to get the total height.
sin = opposite / hypotenuse
sin 36 = x/100
x = 100 sin 36 how high kite is from where it is being held. Add 1 meter to that and you have 100 sin 36 + 1.
