okay so my homework says the measures of two angles of a triangle are given.Find the measure of the third angle please help??????!!!!!!!!!!
Answers
Answer 1
Answer:
Do you remember hearing that the angles of every triangle in the world all add up to the same number ? They always add up to 180 degrees.
If you know the measures of two of the angles, then just take those away (subtract) from 180 degrees, and whatever you have left must be the last angle.
For example, let's take the last one on your list:
54 and 36 are given.
180 minus 54 = 126 then 126 minus 36 = 90 . . ==> the missing angle is 90 degrees =================================================== Another way to do it: One addition and one subtraction.
(54 + 36) = 90 That's the total amount you have to take away from 180.

What value of x makes the equation true? –8.6 = –4.1 + x
A. –12.7
B. –4.5
C. 4.5
D. 12.7
Answers
B. -4.5
You need to isolate x by subtracting -4.1 and to keep the equation equal you need to do this on both sides.
The simple way would be to just try every single one, but I'm gonna tell you how to solve this stuff anyways. So basically, pretend x is a _________ (blank). You've probably done this hundreds of times in school before. Now, you can simply just do -8.6 minus -4.1, and you get the answer -4.5. Make sense? That would mean that it's B.
