PLS HELP<br><br> The perimeter of the square below is 184 m. What is the value of y.
kkurt [141]

we are given

side of square =s=6y+4

now, we know that

perimeter of square = 4*side

so,

perimeter=4*s

now, we can plug s

perimeter=4*(6y+4)

we can set perimeter=184

we get

184=4*(6y+4)

now, we can solve for y

184=4*6y+4*4

we can isolate y on any one side

184=24y+16

24y=168

so, we get

y=7 m...........Answer

In this parallelogram, the measure of     angle b    exceeds the measure of   angle a by 30        What is the measure of  angle
Bess [88]
Angle a +angle b = 180 degrees
angle a + angle a + 30 = 180
2*angle a = 150
angle a = 75degrees
angle b = 75+30 = 105 degrees
now, angle b +angle c = 180
so, angle c = 180-105 = 75 degrees
