Answer:
42.8°
Step-by-step explanation:
The sine rule states that for a triangle with lengths of a, b and c and the corresponding angles which are opposite the sides as A, B and C, then the following rule holds:
Given that points A, B and C forms a triangle with angle A = 65°, distance from A-to-C = 90 m and the distance from B to C = 120 m.
The distance from A to C is the side opposite to angle B. Hence let b = distance from A to C = 90 m.
The distance from B to C is the side opposite to angle A. Hence let a = distance from B to C = 120 m.
Therefore using sine rule:
Answer:
8 = x
y = 29
Step-by-step explanation:
4x + 17 = y + 20 because vertical angles theorem.
y + 20 = 5x + 9 because interior angles theorem.
4x + 17 = 5x + 9 because same side interior angles theorem.
Subtract 9 from both sides and subtract 4x from both sides.
8 = x
Plug 8 in for x and solve.
5 times 8 is 40, plus 9 equals 49. Subtract 20 from both sides and you get 29.
5(8) + 9 = y + 20
49 = y + 20
29 = y
I hope this helps!

Answer:
Step-by-step explanation:
4s + 2j = 68........2j = -4s + 68........j = -2s + 34
3s + 3j = 81
3s + 3(-2s + 34) = 81
3s - 6s + 102 = 81
3s - 6s = 81 - 102
-3s = - 21
s = -21/-3
s = 7 <==== shirts cost 7 bucks
j = -2s + 34
j = -2(7) + 34
j = -14 + 34
j = 20 <===== jeans cost 20 bucks
