Answer = B = 376 degrees - 3x
Solve for x in 2nd equation
times -1 both sides
x-5=6y
add 5
x=6y+5
sub
5(6y+5)+4y=-26
30y+25+4y=-26
34y+25=-26
minus 25 both sides
34y=-51
divide both sides by 34
y=-3/2
sub back
x=6y+5
x=6(-3/2)+5
x=-18/2+5
x=-9+5
x=-4
(-4,-3/2) is solution
Hello!
So you need to find the sin of the angle:
sin20 = x / 10
10 x sin20 = x
x = 3.4
Hope this helps :))
Okay so there are 52 weeks in a year and she runs 12 miles every week so multiply 52 times 12 which equals 624
