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°
It’s slightly closing in so it would be 85 as in the answer b)
ANSWER
4 : 5
EXPLANATION
We have the ratio 16 : 20 and we want to reduce it to lowest form.
This means that we have to factor out any number that is common between the two numbers in the ratio.
We have:
The lowest form of the ratio is 4 : 5
