Answer:

length=1.05m

perimeter=2.7m

Step-by-step explanation:

18900 in m^2=1.89 m^2

area=length*width

1.89=length*1.8 m

length=1.89÷1.8

length=1.05 m

perimeter=(l+w) 2

perimeter=(1.05+1.8)2

perimeter=2.85×2

perimeter=2.7 m

Solve for x. Assume that lines which appear tangent are tangent.

NeX [460]

Answer:

x=2

Step-by-step explanation:

The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.

This implies that:

$55=\frac{1}{2}(116x+3-(180-55))$

We need to simplify this ad solve for x to get:

$110=(116x+3-125)$

Group the similar terms to get:

$110-3+125=116x$

232=116x

Divide by 116 to get:

x=2
