Assume triangle JKL is in the first quadrant, with the measure of angle K = 90°. Suppose triangle JKL is a 30°-60°-90° triangle and segment JK is the side opposite the 60° angle. What are the approximate coordinates of point L?

Answer 1

first question here

Answer 2

second one

Answer 3

For a 45, 45,90 triangle the two legs are equal in length, for a 30, 60, 90 triangle, I would suggest finding the length and seeing which has the appropriate sin and cos.

Answer 4

but how???????

Answer 5

Answer 6

Ok well you can find the length for the first problem, which is 5. so for the first it will be to the right by 5 or 7,2.

Answer 7

For the second case perhaps use tan angle = o / a. so tan(60)=5/a, therefore a = 5/tan(60) or a= 2.9 , so 2.9 to the right or 4.9, 2
