Answer:
x≈12.5
Step-by-step explanation:
angle a=90°,angle b=28°,side c=11
a+b+Y=180°
Using
y=62°
Using the law of sines, we calculate unknown side x
c=11, a/c=sin a°/sin y°
a=c*sin a°/sin y°
a=11*sin 90°/sin 62°=12.46
12.46≈12.5
Answer is 12.5
Cos 28 = 11/x
X= 11/cos 28
X= 11/0.8829
X= 12.4589=~ 12.5
Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 + 12) / 4) + 12
C = 3.785 + 12
C = 15.79 meters
Hope this helps! :)
y=3
F(x)=f(-2) so go to -2 on the x axis and then find the y
