Asap! super find each lettered angle measure without using a protractor. state the reason why you gave the measure you did using the correct vocabulary from the unit. m∠a reason: m∠b reason: m∠c reason:

Step-by-step explanation:

a:  70°

Reason:  a is supplementary to the angle that measures 110°, so 180° - 110° = 70°

b:  55°

Reason:  b is vertical to the angle between 100° and 25° (which add up to 125°) and since all of those angles added together have to equal 180°, then the unidentified angle between 100° and 25° = 55°.  b is vertical to that angle so b = 55°

c:  25°

Reason:  c is vertical the angle measuring 25° so c = 25° also.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
