Key Concepts
Trigonometric ratios can be used to solve for missing side lengths of a right triangle when
one side length and one acute angle is known.
Find the length of side AC to the nearest tenth of a foot.
- sin(369) = 1
18 ft
• (18) sin(36°) = (18)
18) sin(36°) = x
10.5801 = x
The length of side AC is approximately 10.6 feet.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

ab will be equal to
