Answer:
Step-by-step explanation:
<u>Heron's Area formula:</u>
A = , where s is semi-perimeter s = 1/2(a + b + c) We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
a² = b² + c² - 2bccos A a² = 77² + 41² - 2*77*41*cos 79 a² = 6405 a = 80 (rounded) <u>Now find the value of s:</u>
s = 1/2(80 + 77 + 41) = 99 <u>Find the area:</u>
A = = = 1549.24
Answer:
1549.5
Step-by-step explanation:
Hello There!
Heron's area formula is
all we have to do is plug in the values
so
so the area of the triangle is 1549.498509
our final step is to round to the nearest hundredth
the answer would be 1549.5

The final answer is 125x^3-100x^2-40x+16 its not factorable
When it says the "x - 1 " is the factor of that function means when you find the root of the phrase x - 1 which is x = 1 , put it in the function then you have to get zero for the answer :
thus :
Thus :
So :
Add both sides 7
There you go...

Answer:
n - 3 ≤ -8
Step-by-step explanation:
n - 3 ≤ -8
3 less than n: n - 3
is no more than: ≤ - 8
