You can work out c first. That's probably the key to the whole problem.
The adjacent side to a 60o angle is 1/2 the hypotenuse
The hypotenuse in this case = 4 Sqrt(3)
Then c = 1/2 (4 sqrt(3))
c = 2 sqrt(3) That means d is not true.
Next work out a.
a is in the same triangle as c and the hypotenuse.
a^2 + c^2 = hypotenuse^2
a = ??
c = 2 sqrt(3)
h = 4 sqrt(3)
a^2 + (2 sqrt(3))^2 = (4 sqrt(3))^2
(sqrt(3))^2 = 3
a^2 + 4 * 3 = 16 * 3
a^2 + 12 = 48
a^2 = 48 - 12
a^2 = 36
a = 6
Now we need to work out d
The side opposite and the side adjacent are equal when opposite a 45o angle in a right angle triangle
d = 6
The last thing to work out is be
a = 6
d = 6
c = ???
a^2 + d^2 = c^2
6^2 + 6^2 = c^2
c^2 = 72
c = sqrt(72)
c = sqrt(6*6*2)
c = 6 sqrt(2)
The answer should be B??? Check this out.

Step-by-step explanation:
7 friends plus himself = 8 persons
Round trip flight cost = &389x8= & 3112
Hotel bill = &249 x 4 rooms 3 nights = &
& 2988
Cost at Observatory desk = & 18.5 x 8= & 148
Cost at base ball viewing venue = 38 x 8 = & 148
Total budget apart from feeding should be = & 6552
Answer:
C. solution:
3(3c-2) = 5(2c-1)
or, 9c-6 = 10c-5
or, -6+5 =<em> </em>10c-9c
or, -1 = 1c
Hence, c = -1.
D. solution:
5(5-2a) = 4(6-a)
or, 25-10a = 24 - 4a
or, 25-24 = -4a+10a
or, 1 = 6a
or, 1/6 = a
Hence, a = 1/6.
Answer:
Ok so im not the best at explaining but its worth a shot
C)25
Step-by-step explanation:
we already know that the formula to find area is
A=l*w
and that every square is 1 square unit.
So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part so you multiply 8*2 to get 16.
In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.
In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.
Add 16+6+3 together because that is the combined area of the 3 parts and we get 25
Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments
