C + 2c + 12 = 75
Combine like terms:
3c + 12 = 75
Subtract 12 to both sides:
3c = 63
Divide 3 to both sides:
c = 21
Area of triangle = 1/2 × base × height
so,
24=1/2*base*4
base=12m

Answer:
P(at least one tail) = 7/8
Step-by-step explanation:
If you flip a coin, you have two outcomes- heads or tails. So let's find all the outcomes for flipping three coins.
H = heads. T = Tails
HHH P(what you want) = <u>number of times it happens</u>
HHT Total number of outcomes.
HTH
HTT P(at least one tail) = <u> 7 </u>
THH 8
THT
TTH
