My bad if I read it wrong but I got 4.17
Step-by-step explanation:
Use the law of sines....(sina/A=sinb/B=sinc/C for any triangle)
What that means is the sine of an angle divided by the length of the side opposite the angle is a ratio that is true each angle/side pair...In this case:
sin90/122=sinc/22 rearrange to solve for sinc
sinc=(22sin90)/122 now take the arcsin to solve for c
c=arcsin[(22sin90)/122]
c≈10.388857815469611987441020361405
c≈10.39° (to nearest hundredth of a degree)
The answer would be C because it’s the only fraction that does not equal 0.4

▹ Answer
<em>D. 3x² + 13x - 56</em>
▹ Step-by-Step Explanation
(x + 7)(3x - 8) (<em>Using FOIL method)</em>
x * 3x - 8x + 7 * 3x - 7 * 8
3x² - 8x + 7 * 3x - 7 * 8
3x² - 8x + 21x - 56
3x² + 13x - 56
Hope this helps!
