Help! I will become fan and give medal.

What do you need?

OpenStudy (anonymous):

One angle of a right triangle measures fifty-five degrees. Which could be the measure of one of the other angles?

OpenStudy (anonymous):

So a triangle measures up to 180 degrees right?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Is this an acute triangle, obtuse or right?

OpenStudy (anonymous):

i have choices if you want them

OpenStudy (anonymous):

Sure,m throw them up.

OpenStudy (anonymous):

right

OpenStudy (anonymous):

35, 45, 55, 125

OpenStudy (anonymous):

Okay so you know that a right angle is 90 degrees right?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

And you already have 55 for another angle, so what do you think you should do to get 180 and find that last angle?

OpenStudy (anonymous):

125?

OpenStudy (anonymous):

ohh i get it

OpenStudy (anonymous):

thanks i have more questions if u have time

OpenStudy (anonymous):

Hold on you did that wrong.

OpenStudy (anonymous):

oh sorry

OpenStudy (anonymous):

Lets go back to the first one

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

So, 90 is right angle, right? and you have 55 for the other?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

So, should we add or subtract those?

OpenStudy (anonymous):

subtract

OpenStudy (anonymous):

which is 35!

OpenStudy (anonymous):

You would actually add 90+55 and get 145. Then subtract 180-145

OpenStudy (anonymous):

and you get 35. correct. :)

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

yay thanks

OpenStudy (anonymous):

No problem.

OpenStudy (anonymous):

i have another one

OpenStudy (anonymous):

if you have time

OpenStudy (anonymous):

Yeah go ahead!

OpenStudy (anonymous):

Use the Triangle Sum Property to find the measure of angle y.There are two triangles. The two triangles overlap and share one angle, x. The smaller triangle’s angles measure, x degrees, thirty-three degrees and y degrees. The larger triangle measures x degrees, forty-nine degrees and one hundred-fifteen degrees. a, 124 b, 131 c, 115 d, 16

OpenStudy (anonymous):

The sum of the measures of the interior angles of a triangle is 180°.

OpenStudy (anonymous):

Definition ^

OpenStudy (anonymous):

ok..

OpenStudy (anonymous):

Okay so do you see that 115 on the bottom left?

OpenStudy (anonymous):

yes 180-155?

OpenStudy (anonymous):

Hold on. So you know y is going to be 115 too because those sides are adjacent.

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

thats the answer?

OpenStudy (anonymous):

Yes sir!

OpenStudy (anonymous):

oh that was easy

OpenStudy (anonymous):

Geometry is easy, people just tend to overthink it.

OpenStudy (anonymous):

thank you very much for helping!

OpenStudy (anonymous):

My pleasure, have a good day man!

OpenStudy (anonymous):

you too
