Height=25m
diameter=1.8m
so radius=0.9m
soil dugged out to.make well=vol.of well
=pi×r^2×h
=3.14×0.9×0.9×25
=3.14×25×0.81
=63.585m^3
Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1

Answer:
m2=125°
m3=65°
m4=125°
m5=65°
m6=125°
m7=65°
m8=125°
i know the reason in French if you want
Step-by-step explanation:
m2=180-65=125°
m2 = m4 =125°
m3 =m1 =65°
m3= m5 =65°
m4 =m6=125°
m7=m5 =65°
m8=m6=125°
