I think it is E .I am thankfull in helping you
Answer:
F=73.74 degrees
Step-by-step explanation:
sin=opposite/hypotenuse
opp=24 hyp=25
sin(F)=24/25 (to find angle have to use inverse sin)
sin-1(24/25)=73.74
11. y=-1/3x-4
Plug the slope into m in y=mx+b and then plug in your point and solve for b. You get C
12. Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9
13. Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13
Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
= 0.6
100 % = 0.6 x 100
= 60 min
It takes her 60 mins or 1 hour to finish building the wall.
Hope this helps :))
