Answer:
x=25
Step-by-step explanation:
60+70=130
180-130=50
50/2=25
∠F +∠E + ∠D = 180 {Angle sum property of triangle}
2x +70 + 60 = 180
2x + 130 = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
ummm do you know how to say it in englishh,imight be able to halpo if you dooo
a+pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
a= 353.25ft^2
