Answer:
34 i think i got it really wrong but...
Step-by-step explanation:
A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.
b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.
Hope this helps :)
Answer:
Each coins are quarters of <u>6</u>, nickels of <u>18</u> and the dimes of <u>9</u>.
Step-by-step explanation:
<u><em>There is a mistake in question.</em></u>
The question must be:
A collection of 33 coins having dimes quarters and nickels, <u>there are 3 times as many nickels as quarters, and one-half as many dimes as nickels</u>, all of the coins equal $3.30 how many coins of each kind are there?
Now, to find the number coins of each.
Let the quarters be
.
Nickels be
.
And the dimes be
.
So, the total collection of coins are:

On adding the fractions we get:


Multiplying both sides by 2 we get:

Dividing both sides by 11 we get:

Thus, quarters = 6.
Nickels = 
Dimes = 
Therefore, each coins are quarters of 6, nickels of 18 and the dimes of 9.
Answer:
from the image above
Triangle ABE = Triangle ADE
AE = AE ( common).
angle AEB = angle AEO ( each 90°)
AB = AD ( given).
by side angle side criteria
so area of ABE = area of ADE
similarly,
BC = DC ( given)
BEC = DEC ( 90°)
EC = EC ( 9m each)
so area of BEC = Area of DEC
