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 =
(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
We are given that there are:
Black helmets = 3
Red helments = 2
Let us start from the guy at the back. The guy at the back
can see the two helmets in front of him. If the two helmets in front of him are
red, then he can certainly say that his helmet is black since there are only 2
red helmets. Since that is not the case, then therefore he can either be black
or red. Therefore this also means that at least 1 of the 2 guys in front of him
has black helmet.
<span>Since the remaining two should have at least 1 black,
therefore the middle guy can see that the helmet in front of him is not red (so
1st guy is black). Because if the guy in front of him is red, then
he can know that he must be black since remember, at least one of the 2 front
guys must be black, but the middle guy cannot say that. Therefore the 1st
guy knows he has a black helmet.</span>

Answer:

Step-by-step explanation:
The Exponential Product rule tells us that...

Therefore,
.
Therefore, 
Use the formula for the area of a parallelogram:

Plug in what we know:

Convert both of them into improper fractions. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

Now multiply the numerators and denominators together:

Convert it back into a mixed number. 14 goes into 555 thirty-nine times. 14 * 39 = 546. 555 - 546 = 9. So we have 39 wholes and 9 left over, or:

So this is the area of the parallelogram.
