OpenStudy (anonymous):

OpenStudy (anonymous):

please

OpenStudy (imstuck):

Look at the angles with the values in number 8. do you know what kind of angles those are?

OpenStudy (anonymous):

symmetrical?

OpenStudy (imstuck):

vertical. Do you know anything about vertical angle properties?

OpenStudy (anonymous):

no

OpenStudy (imstuck):

Vertical angles, by definition, are equal to one another.

OpenStudy (anonymous):

the first one is...53 (:

OpenStudy (imstuck):

You use the two values they gave you, and since they are equal to one another, you have this as an equation: 3x-10=149

OpenStudy (anonymous):

thanks guys

OpenStudy (imstuck):

Solve that equation for x and you will have the answer to #8.

OpenStudy (imstuck):

Now for #9, unless you don't need #9...

OpenStudy (anonymous):

second one i believe is A

OpenStudy (anonymous):

ok and can u just give me the equation and ill solve it @IMStuck

OpenStudy (anonymous):

like u did for 8

OpenStudy (imstuck):

Its a 2-part thing...x and y. for the x part, the two angles are vertical again, so the equation would be 7x+7=112 and solve for x. What do you get for x?

OpenStudy (imstuck):

yes the same way so far as in #8

OpenStudy (imstuck):

what is x?
