Please help!!! this is due tomorrow!!1!!11!!!1!
Ronch [10]

Answer: m<KHL = 37 degrees.

m<GHK = 53 degrees

Step-by-step explanation:

<CHD and <KHL are vertical angles. They are equal in measure. m<CHD is 37 degrees, so m<KHL is also 37 degrees.

Notice <GHL is a 90 degree angle (because the lines that form it are perpendicular) and <GHL is made up of two angles: <GHK and <KHL.

m<GHK + m<KHL (37) = m< GHL (90 degrees)

Subtract 37 from both sides.

m<GHK = 53 degrees

The weight of an object on the moon varies directly with its weight on the earth. If an object weighing 95 lbs on the moon weigh
Luda [366]
ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
m \propto \: e
We introduce the constant of proportionality to obtain,

m = ke

When, m=95, e=570,

This implies that,

95 = 570k
k = \frac{95}{570}

k = \frac{1}{6}

The equation now becomes,

m = \frac{1}{6} e

We want to find e, when m=2700,

m = \frac{1}{6} \times 2700

m =450lb
