These problems are rather easy. What you need to remember is that the parallel line segments will always contain the same number so the angle (65) on b2 would be the same angle for a2, bt at. so now to find the angle for b1 and a1 so we would subtract 65( the angle for B2) by 180 (the angle for a line) which would come out to be 115.
i hope this helped you, if not heres a link to a website that explains what i tried to explain.
Answer:
≈ 7
Step-by-step explanation:
Let x is the <span>unknown number
</span><span>quotient of an unknown number and 12 : x/12
</span><span>49 more than the quotient of an unknown number and 12 : x/12 + 49
so equation:
</span>x/12 + 49 = 53
Answer:
Step-by-step explanation:
x is the side opposite the angle of 12 degrees
we know the hypotenus is 20 ft
we don't know what the side length that is adjacent to the angle
----------------
ADJ/HYP = cos (of the angle)
OPP/HYP = sin (of the angle)
sin/cos = tan (of the angle) = ( OPP/HYP) / (ADJ/HYP) = OPP/ ADJ
How would we solve for x the side opposite the angle?
So who is right?
By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
