<u>ANSWER</u>
The point lies on the straight line
<u>EXPLANATION</u>
The given line is . It can be observed that the given straight line is in the point-slope form.
We can rewrite the equation in the point-slope form to obtain,
.
When we compare this to the general point-slope form, which given by the formula;
,
We can observe that,
and
.
Hence the point, lies on
Answer:
acute: 7, 9
right: 8, 10
obtuse: 5, 6
Step-by-step explanation:
When you have a number of identical calculations to do, it is convenient to do them in a spreadsheet. You only need to enter the formula once and copy it as many times as needed.
The attachment shows the "sum of squares" calculation and comparison to the square of the longest side. When the sum is too small, the longest side is longer than needed for a right angle, so the triangle is obtuse. When the sum is too great, the longest side is too short for a right angle, so the triangle is acute.
We have skipped the tedious arithmetic and shown the results in the attached table.
