Something here is not right. A triangle has a total of 180 degrees. Given A and B, the 3rd angle C = 35o. Maybe you mean c = 15; the length of side c, which is opposite angle C. Then the law of sines gives:

a/sin 45 = 15/sin 35
a = 15 sin 45/sin 35
= 15 X 1.2328
= 18.492, approx

A kite has a perimeter of 70. One of the shorter sides measures 16 centimeters. What are the lengths of the other three sides?
KonstantinChe [14]
The sum of a long side and short side will be half the perimeter, so the long side has length (70/2) -16 = 19 cm.

The other three sides are 16 cm, 19 cm, 19 cm.

Eliminate parentheses using the distributive property.

... -1 -7g +42 +6g = 36

... 41 -g = 36 . . . . collect terms

... 41 -36 = g . . . . add g-36 to both sides

... 5 = g . . . . . .. . . your answer
