You have to use Pythagorean's theorem to find the missing side measure. 41^2=40^2 + w^2. 1681 = 1600 + w^2. 1681-1600=w^2. 81=w^2 and w = 9. That's an odd triangle, but accurate! Now use the cos definition of cos x = 9/41, and cos x = .2195. Now use the inverse function on your calculator in degree mode to see that the angle x is 77.3 degrees.
Answer:
x= 7
Step-by-step explanation:
add (12x+1) and (5x-3) which becomes 17x-2 and then set that equal to 117 and solve. move the 2 to the right side of the equation which becomes 17x=119 and then divide 119 by 17 which x equals 7.
plug in 7 for x to make sure you get 117
14: plug in the points to y1-y2/x1-x2 (equation for slope)
20-13/x-11= 7/3
What value of x makes x-11=3 true?
Add three to each side to get x=14
Answer: -8
Step-by-step explanation: If he scored -2 four times then his score would be -8 (-2×4).
