Circle theorems please help

Mathematics
1 answer:
suter [353]2 years ago
6 0

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = \frac{1}{2} (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28

Will give brainliest!!!!<br>Explain how solving -7y &gt; 161 is different from solving 7y &gt; -161.
Jlenok [28]

To solve -7y > 161, we divide both sides by -7 and we get y < -23. The inequality sign flipped because we divided both sides by a negative number.

To solve 7y > -161, we divide both sides by 7 and it leads to y > -23. The inequality sign does not flip in this case, because we are not dividing both sides by a negative number.

The similarities is that we end up with -23 on the right side, but the inequality signs are different.

The total cost of attending a state university is $19,700 for the first year. • A student's grandparents will pay half of this c
Temka [501]

Answer:

The student will have to save $404.2 minimum monthly

Step-by-step explanation:

Given that the total cost for the first year= $19,700

The grandparents paid half the amount = 1/2(19700)= $9850

The remaining balance to be paid is

19,700 - 9850=$9850

If an athlete paid $5000

The the remaining balance to be paid = 9850-5000=$4850

For the student to clear this amount in 12 months he must save

monthly 4850/12= $404.166

Hence the minimum amount to be saved per month is $404.2
