Formula for triangle: A=1/2 bh
48=1/2 b6
Divide 6 by both sides.

8=1/2b
Multiply both sides by 2 to eliminate the half
B=16


Check ur work:

48=1/2(16)(6)
Half of 16 is 8
8 times 6 =48

Area of a triangle  = 1/2 bh
48 = 1/2 b * 6
48/6 = 1/2 b
8 = 1/2 b
16 = b

The answer is (C) 16.

Find the two smallest possible solutions to part 1a​

<h3>Answer: A. 5/12, 25/12</h3>

============================

Work Shown:

12*sin(2pi/5*x)+10 = 16

12*sin(2pi/5*x) = 16-10

12*sin(2pi/5*x) = 6

sin(2pi/5*x) = 6/12

sin(2pi/5*x) = 0.5

2pi/5*x = arcsin(0.5)

2pi/5*x = pi/6+2pi*n or 2pi/5*x = 5pi/6+2pi*n

2/5*x = 1/6+2*n or 2/5*x = 5/6+2*n

x = (5/2)*(1/6+2*n) or x = (5/2)*(5/6+2*n)

x = 5/12+5n or x = 25/12+5n

these equations form the set of all solutions. The n is any integer.

--------

The two smallest positive solutions occur when n = 0, so,

x = 5/12+5n or x = 25/12+5n

x = 5/12+5*0 or x = 25/12+5*0

x = 5/12 or x = 25/12

--------

Plugging either x value into the expression 12*sin(2pi/5*x)+10 should yield 16, which would confirm the two answers.
