OpenStudy (boldjon):

OMG I"M HERE WHAT IS IT

OpenStudy (hari5719):

question ??

OpenStudy (sleepyjess):

Hello! Welcome to OpenStudy! What can I help you with? ^_^

OpenStudy (anonymous):

Its a math question and the question is If triangleABC is congruent to triangleDEF, m angle A = 55°, and m angleE = 25°, what is m angleC? (1point) 25° 55° 80° 100°

OpenStudy (sleepyjess):

First, we need to figure out which angles correspond to each other. On Triangle DEF, which angle would angle A correspond to? |dw:1451529945205:dw|

OpenStudy (anonymous):

??? Idk

OpenStudy (sleepyjess):

Look at the angle labels, which angle is the same as angle A

OpenStudy (anonymous):

D

OpenStudy (sleepyjess):

Yes! So angle A and angle D are congruent, they are both 55 degrees. Now which angle is the same as angle B?

OpenStudy (boldjon):

I TOLD U

OpenStudy (boldjon):

D

OpenStudy (anonymous):

E which both the angles are 25° now what is m angle C

OpenStudy (sleepyjess):

I'm confused now

OpenStudy (sleepyjess):

Good! Do you know what all of the angles of a triangle add up to?

OpenStudy (boldjon):

E

OpenStudy (boldjon):

becuz of the triangle

OpenStudy (boldjon):

and the sides

OpenStudy (boldjon):

it's all clear so it's d

OpenStudy (anonymous):

What's the answer A) 25° B) 55° C) 80° D) 100°

OpenStudy (sleepyjess):

How many degree are there in a triangle household?

OpenStudy (anonymous):

What's the answer?

OpenStudy (sleepyjess):

*degrees

OpenStudy (anonymous):

What would be the answer cause I'm on a tight schedule PLEASEEEE?

OpenStudy (sleepyjess):

There are 180 degrees in a triangle. Now, what is 180-25-55?

Zeronknight (zeronknight):

@boldjon Please don't jump in, you aren't giving full explanations on the problem, in fact you keep just say "It's so obvious". Please move on to another question, someone is already helping this person.

OpenStudy (boldjon):

-_- hata

OpenStudy (boldjon):

hmph!

OpenStudy (sleepyjess):

Once you subtract that out, that will be the answer for angle C

OpenStudy (anonymous):

Al three angles of a triangle will ALWAYS add up to 180 degrees. The question has given you the measurement of two angles, so once you add those two, you need only subtract the total amount from 180 in order to get the remaining angle. Your limit is 180 degrees, so if you add the two angles you have and subtract from 180, whats left is your answer.

OpenStudy (anonymous):

180 - (55 + 25)
