Answer:
See step by step
Step-by-step explanation:
The student found the cosine of angle A not the sine. Sine is Opposite/Hypotenuse. This student found Adjacent/Hypotenuse. The correct answer is Sin A= 12/13.
What is the middle of 6 and 12- 6, 7, 8, 9, 10, 11, or 12?
The area of the enclosed space is given by the equation
(6+2x)² = 169
We can take the square root of both sides, since 169 is a perfect square:
√(6+2x)² = √169
6 + 2x = 13
Subtract 6 from each side:
6 + 2x - 6 = 13 - 6
2x = 7
Divide both sides by 2:
2x/2 = 7/2
x = 3.5
