M<GJI=(x+60)°=?
We need to find x. The angle GJI and FJH are opposite by the the vertex, then they must be congruents:
(x+60)°=(5x)°
x+60=5x
Solving for x
x+60-x=5x-x
60=4x
60/4=4x/4
15=x
x=15
Replacing x by 15 in m<GJI:
m<GJI=(x+60)°=(15+60)°→m<GJI=75°

Answer:
Length = 12yards
Width = 14yards
Sum = 26yards
Step-by-step explanation:
Let assume the play ground is rectangular in form.
Area of a rectangle = length × width
Given area of the playground = 168yd²
If the width of the playground is 2yd longer than its length, then:
W = L+2
Substituting W = L+2 into the formula above we have:
A = L × (L+2)
A = L²+2L
168 = L²+2L
L²+2L-168 = 0
L²+14L-12L-168 = 0
L(L+14)-12(L+14) = 0
(L-12)(L+14) = 0
L-12 = 0 and L+14 =0
L = 12 and -14
Taking the positive length, L = 12yards
If Length = 12yards
W = L+2
W = 12+2
Width = 14yards
Sum of the length and width will be:
L+W= 12+14
= 26yards
