Refer to right triangle ABC with C = 90 degrees if a=6 and c=18, find b
1 answer:
Answer:
16.97
Step-by-step explanation:
To solve for a missing side in a right angles triangle, we solve using Pythagoras Theorem.
Pythagoras Theorem =
a² + b² = c²
Where c = Hypotenuse = Longest side
From the question above,
a=6 and c=18,
Hence,
6² + b² = 18²
b² = 18² - 6²
b² = 18² - 6²
b² = 324 - 36
b²= 288
Square root both sides
b = √288
b = 16.970562748
Approximately b ≈ 16.97

Answer:
Answer:.1.77
Step-by-step explanation:
e^x = 5.9
Take the natural logarithm of both sides
x = ln (59/10)
x = 1.77
(found this)
<span>2n^2 - 7n - 3 = 0
a = 2
b = -7
c =-3
Then use the Quadratic formula:
x = [-b +-sqroot(b^2 -4*a*c)] / 2*a

X * 0,8 = 259,2 <=>
x = 258,2/0,8 <=>
x = 322,75
The total budget was 322,75$
