Answer: D) 2
<u>Step-by-step explanation:</u>
The sum of two sides of a triangle must be greater than the third side
Let x represent the unknown side
Then 4 + 6 > x → x < 10
and 4 + x > 6 → x > 2
Therefore; 2 < x < 10
A) 6 is between 2 and 10
C) 3 is between 2 and 10
B) 4 is between 2 and 10
D) 2 is NOT between 2 and 10
Step-by-step explanation:
We know that m∠1 is 110°. If we look at m∠7 closely, we can see that while m∠1 is an obtuse angle (greater than 90° but less than 180°), m∠7 is an acute angle (less than 90°).
Now, we can eliminate 110° and 180° since we know that m∠7 is an acute angle. There are only 2 choices now: 40° or 70°.
If you flip the image around, you can see that the angle is slightly less than 90°, so it has to be 70°.
Answer:
2) 70°
4. A) 95°
5. B) 49°
You add
46° + 39° = 85°
180° - 85° = 95°
You add
89° + 42° = 131°
180° - 42° = 49°
Hope this Helps!!
You would bring the division over to to other side. When we switch it to the other side, it turns into a multiplication (the opposite of division). So we go from:
102 / 3 = 34
to
102 = 34 * 3
Which is C for your multiple choice! :)
