90 POINTS!!!!! Given: KLIJ inscr. in k(O),m∠K = 64°, measure of arc LI = 69°, measure of arc IJ = 59°, measure of arc KJ =97°
Kay [80]

In any cyclic quadrilateral, angles opposite one another are supplementary, meaning

m\angle K+m\angle I=m\angle L+m\angle J=180^\circ

and given that \boxed{m\angle K=64^\circ}, we have \boxed{m\angle I=116^\circ}.

By the inscribed angle theorem,

m\angle JLK=\dfrac12m\widehat{KJ}

m\angle ILJ=\dfrac12m\widehat{IJ}

and since

m\angle L=m\angle JLK+m\angle ILJ

we have

m\angle L=\dfrac{97^\circ+59^\circ}2\implies\boxed{m\angle L=78^\circ}

and it follows that

m\angle J=180^\circ-m\angle L\implies\boxed{m\angle J=102^\circ}

How long will it take Greg to earn $500.00 round to the nearest hour
Mrrafil [7]

Answer:

56 hours

Step-by-step explanation:

we know that  

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

k=y/x

For (3,27) ----> k=27/3=9\ \$/h

For (9,81) ----> k=81/9=9\ \$/h

For (21,189) ----> k=189/21=9\ \$/h

The constant of proportionality k is 9

The linear equation is

y=9x

For y=$500

substitute in the equation and solve for x

500=9x

Divide by 9 both sides

x=56\ hours
