kattie and matt are both flying kites on a breezy day. the string of katies kite is extended 864 feet, and her kite makes a 38 angle of elevation with the ground. the string of matt's kite is extended 725 feet, and his kite makes a 40 angle of elevation with the ground. Whose kite is flying higher in the sky

Kattie's kite is flying higher

Step-by-step explanation:

Let the height of each kite be h.

The h is opposite to angle of elevation and the sting length is hypotenuse of the formed triangle.

Kattie's kite:

h/864 = sin 38°h = 864 sin 38°h =  532 ft (rounded)

Matt's kite:

h/725 = sin 40°h = 725 sin 40°h = 466 ft (rounded)

Kattie's kite is flying higher as 532 ft > 466 ft

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
