Answers either A) 32 or B) 46.
OpenStudy (amistre64):
thats an eyesore fer sure, but you just need to add up the given measures to 360 and solve for x
OpenStudy (amistre64):
then yvz +zvx = 180

you can prolly cut down a bit by adding the "bottom" 3 angles to 180 just as well

OpenStudy (amistre64):
(3x+5) + (7x+15) + (8x-2) = 180
18x+5+15-2 = 180
OpenStudy (anonymous):
was 46 my answer?
OpenStudy (amistre64):
18x +18 = 180
18(x +1) = 180
x +1 = 10
x = 9
OpenStudy (anonymous):
?? 9 isnt an option..
OpenStudy (amistre64):
(15x - 1) + A = 180
A = 180 - (15x - 1)
A = 180 - (15(9) - 1)

of course 9 isnt an option ... its not asking you the value of x, but you need to determine x to solve the rest of it
OpenStudy (anonymous):
46 was my answer. -_- ..
OpenStudy (amistre64):
46 is correct yes
