Answer:
Go to desmos.com/calculator
Step-by-step explanation:
It has a graphing calculator and it super easy to plug in.
Some of the problems are in scientific notation, which if you don't know how to do, I will try to explain, when you see for example 1 x 10^3, what it is saying is basically 1 x 10 x 10 x 10 so in that case 1,000, simple trick is to look at what ever number is in the top right, then add that many zeroes. So this is most likely supposed to be a division problem. if you need more help message me.
hi ! so the answers are below ...
<h3>1. we need to add both angles to find angle QST</h3><h3> <u>5</u><u>2</u><u> </u><u>+</u><u> </u><u>4</u><u>7</u></h3><h3> <u>=</u><u> </u><u>9</u><u>9</u></h3>
<h3>2. since the angles are on a straight line, to find the angle NPM we need to subtract the given angle with 180⁰ since the total of a straight line is 180⁰ ( hope you understand )</h3>
anyways...
<h3> <u>1</u><u>8</u><u>0</u><u> </u><u>-</u><u> </u><u>7</u><u>9</u></h3><h3> <u>=</u><u> </u><u>1</u><u>0</u><u>1</u></h3>
hope that helped and let me know if you have any more questions :)
Can you post a more clear picture
