Find the measure of the indicated angle

Answers

Answer:

? = 110

Step-by-step explanation:

We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.

All angles of a triangle always adds up to 180

Add all the known angles 25 + 45 = 70

Than subtract 180 - 70 = 110

The answer for the indicated angle is 110 degrees

What are like terms? How do you combine them? Whats an example
I NEED HELP ASAP PLEASE

Answers

Answer:

like terms are terms that have the same variable

Step-by-step explanation:

when combining like terms we add their coefficients for example 4x + 5x = (4+5)x=9x

Examples of like terms are:
5d & 7d
3x & 2x
10 & 4
7 & -6

You combine them by simply doing what the equation tells you:
For example:
4d + 6 - 2d + 10
This would simplify to:
2d + 16

This is because I took the like terms, 4d & -2d, and 6 + 10.

4d - 2d = 2d
6 + 10 = 16

So the answer would be:
2d + 16
