Move the decimal twice to the right to get a decimal (it should start behind the 2 and end up in front of the 7)
For a fraction just put it over 100 72/100
[7×(-3)] × (-2)²
= (-21) × 4
= -84
Answer:
Measure 8 is 135°
Step-by-step explanation:
Measure 1 and Measure 8 are alternate exterior angles.
Answer:
No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.)<em> a + b > c</em>
2.)<em> a + c > b</em>
3.) <em>b + c > a.</em>
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if <em>all</em> the two side lengths of a triangle is greater than the third side, then it makes a triangle.
