Question

If m∠2 = 108° and m∠P = 55°, then m∠O =



17

27

43

53

Answer 1

Alright now words....

angle 2 is 108....and angle 1 is supplementary to that..so they add to 180...so angle 1 will be

180 - 108 = 72

now...we are given that P = 55...so we have 2 angles of a triangle...(72 and the 55) and we know the 3 angles will add to 180...so our last angle (angle O) will be

72 + 55 = ?

and then when you find out what the ? is....we do

180 - ? = angle O

Answer 2

ummmmmm

Answer 3

43?

Answer 4

try again...

Answer 5

and hang on...does what I say make sense?

Answer 6

only kind of. im kinda in the wrong math class and have no idea what im doing

Answer 7

27?

Answer 8

Oh oh okay....here a good summary of this...

a triangle...has interior angles that add to 180

so we know here, angle 1 + angle P + angle O = 180

We are given 1 angle inside the triangle....P = 55

we are given an angle OUTSIDE the triangle = 108 but to get the angle INSIDE we see that the 2 angles are supplementary which means they add up to 180...so angle 2 = 108 meaning angle 1 would be 180 - angle 2....which is 180 - 108 = 72

Now...we have 2 angles from inside the triangle...

Angle P = 55
Angle 1 = 72
Angle O would complete the 3 angles that add up to 180...so

We have so far 55 + 72 = 127......

we have 127 out of the total 180 degrees that we need....so angle O would be the difference...

180 - 127 = 53 degrees
