Answer:
haha
Step-by-step explanation:
first off thats not 50 points
A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)
A = 288 + 27.6 + 84
A = 399.6 m²
The 30,60,90 - the hypotenuse is equal to twice the length of the shorter leg , the hypotenuse side =2x , the shortest side =x and the straight side is x square root 3
A mixed number is one that has an integer along with a proper fraction, so that would be (for this improper fraction):
50/12 = 4 1/6
12 goes into 50, 4 times with a remainder of 2
you get: 4 and 2/12, but 2/12 can be reduced further to 1/6
so that's how i got the answer of 4 1/6
