The answer is B
Use sin rule to find the answer.
base of smaller triangle = 7 = base of larger triangle

(7/sin45) x sin90 = x

Anon25 [30]
2l + 2w = 132
l = 3w + 2

2(3w+2)+2w=132
6w + 4 + 2w = 132
8w + 4 = 132
8w = 128
w = 16

l = 3(16) + 2
l = 48 + 2
l = 50

2(50) + 2(16) __ 132
100 + 32 = 132

Find A, B, and C <br> Help ASAP!<br> {10 points up}
Rama09 [41]

so we have a 60-30-90 triangle (top one)

so since we know 6 is x (the side on the right angle and 60 degrees)

b is 2x or 2(6) = 12

a is x√3 = 6√3


for C I need to use a 45 45 90 triangle

Since b is 12 and its x√2  to find x we should write it as

x√2 = 12

√2     √2  divide by √2

x = 12/√2  but we must rationalize the denominator

12/√2  times √2/√2  = 12√2/2 and that's c

Bad White [126]

Answer:

a) we have the numbers 0, 2, 3, 5, 5. The mean and the median are both 3

b) we have the numbers 0, 0, 3, 5, 7. The mean and the median are both 3

In both cases the mean and the median are 3, but the mode differs. The mean and the median do not uniquely determine the mode.
