B.
sin^2x + cos^2x =1
hence Sin^2x-1 = - cos^2x
Hello :) ok so to find AC you would have to use sin. It would be sin70= x/4. To find AC you would have to multiply 4 by sin70 which is 3.758 or to the nearest hundredth would be 3.76. I hope I helped, if you need a more in depth explanation lmk
Answer:
35.w/g=m
36. P=1/2Q-15
37. R=IV
38. b=-mx+y
39. a) t=-d-e+f
b) t=19.175
40. No, X=-2.4
Step-by-step explanation:
Explanation for 40:
2(x-4)-4x=-6x+9x+4
first do the parentheses
2x-8-4x=-6x+9x+4
next combine like terms
-2x-8=3x+4
add 2x to each side
-8=5x+4
subtract 4 from each side
-12=5x
divide both sides by 5
x=-2.4
