see <DEC = 3x + 10 and <AEB = 5x also <DEC = <AEB vertically opposite angles so 3x + 10 = 5x get x then get the <AEB and <DEC and after tht u see <AED + <DEC = 180 (straight line)

OpenStudy (anonymous):

so whats the measure of AED?

rishavraj (rishavraj):

@byronichero I am definitely not gonna tell u the answer...so sorry.... u need to solve it :)) give a try.... I mentioned all the steps :))

drum role

OpenStudy (anonymous):

this is an obtuse angle right so that eliminates a and b and it is way bigger than 90 degrees so it can't be c so it can only be d.

@rishavraj what does what mean

rishavraj (rishavraj):

see 3x + 10 = 5x so 2x = 10 x = 5 so <DEC = 3*5 + 10 = 25 so now <DEC + <AED = 180 u got the value of <DEC , get the value of <AED
