I would use the Law of Sines to solve this problem.
The angle next to the 58 degree angle is 122 degrees. The side opposite this angle is 3.72 km.
The angle we need to find is at the cave. The side opposite this angle is 2.60 km.
(Sin 122/3.72) = (Sin x/2.60)
Cross multiply to solve.
3.72 Sin x = 2.60 Sin 122
Divide both sides by 3.72
Sin x = (2.60 Sin 122)/3.72
Sin^-1 x = (2.60Sin122)/3.72
x = 36 degrees
Answer: 12
Step-by-step explanation: V of prism = S of triangle*Height of prism
height of prism is 30
S of triangle = a/2*<em>h</em>( a =18 cm)
3240=30*(18/2)*<em>h</em>
<em>h</em>=3240/(9*30)=12
20 x 2=40
10 x 4=40
8 x 5= 40
so 2 bags of balloons
4 bags of horns
5 packages of candy
Answer:
Step-by-step explanation:
1. (a+3)(a-3) = a²+3a-3a-9 = a²-9
2. a linear equation consists of a polynomial of degree one.
