The formula for the area of a triangle is A = (base · height)/2, but when we look at this problem, there's no base or height!
Looking at the triangle on the right, we can use the Pythagorean Theorem to find the height:
h² + 16² = 20²
h² + 256 = 400
h² = 144
h = ± 12
In this case, the height is 12 because you can't have negatives when you are working with lengths of sides and other things like this in geometry.
So now we've found the height, but we still don't know the full base! So, we can use the height that we just found to use the Pythagorean Theorem for the left triangle!
B² + 12² = 15²
B² + 144 = 225
B² = 81
B = ±9
So once again, our answer is just 9.
But, because the base is CB, we have to add:
b = 9 + 16
b = 25.
Now we have the base and height, so we can put them into our formula to solve for the area of the triangle:
A = (25 · 12) / 2
A = 300 / 2
A = 150
Answer:
It can save $ 92.5.
Step-by-step explanation:
Total amount of bill is = $1850
Offered discount on the total bill on cash payment with in 10 days = 5% of the bill .
It can save the discount offered on cash payment which is obtained by finding the percentage of total bill
Discount in dollars = 5% of $1850
= 0.05 x 1850
= $92.5
therefore it can save $92.5 of the total bill payment if it is paid with in 10 days of billed date to avail the discount offered.
$ 92.5 is the answer .
<span>If we are talking about human behaviors, one can say that if we add a diet full of fat and sugars, plus no physical exercise, plus lots of hours watching television the total result will be equal to obesity, diabetes and high cholesterol.</span>
The answer is 28. 7x2=14 and then 14x2=28. Remember PEMDAS
