What is the measure of angle C? A. 28° B. 62° C. 90° D. 10°

OpenStudy (amistre64):

if you add up all your angles they should give you 180 to solve for x

OpenStudy (amistre64):

so thats what; 13x+50 = 180 ?

OpenStudy (amistre64):

13x = 180 - 50 13x = 130 x = 130/13 = 10 so replace x with 10 to solve for C

OpenStudy (amistre64):

well, its NOT 62 :)

OpenStudy (anonymous):

then what ? i dont get this stuff .

OpenStudy (anonymous):

A. 28 degrees

OpenStudy (amistre64):

then you really need to sit down with a tutor if you are not comfortable with the basic math operations of adding and multiplyiing.

OpenStudy (anonymous):

angle A looked like 90 degrees. To be save the following was solved for x: 6 x + 30 + 5 x + 12 + 2 x + 8 = 180 x=10, 2x+8=28 degrees.

OpenStudy (amistre64):

all that you do in math is based on those operations

"save" should have been typed, "safe".
