Answer:
We consider a triangle ABC as attached in the answer.
We draw a line parallel to AB that passes through point C.
Angles C and C' are vertical angles, therefore ∠C = ∠C'.
Angles B and B' are corresponding angles, therefore ∠B = ∠B'.
Angles A and A' are corresponding angles, therefore ∠A = ∠A'.
it can be seen that angle sum ∠A + ∠B + ∠C is equal to the angle sum ∠A' + ∠B' + ∠C'.
The three angles A', B', and C' form together a straight angle so, their angle sum is 180°. But then the angle sum ∠A + ∠B + ∠C must also be 180°.
This proofs that sum of angles of a triangle is equal to 180.
<span>P(x)= 75,000*(x-1940)^(1/3)
then the P = 245000 means
245000 = </span>75,000*(x-1940)^(1/3)
(245000/75000)^3 + 1940 = X
X ≈ 1974

Answer:
b=45/4
Step-by-step explanation:
This is a special triangle 30-60-90.
In big triangle hypotenuse 15, short leg x=(hypotenuse/2), x=15/2.
In smallest triangle :
1. This is also special triangle 30-60-90
2. x=15/2 hypotenuse
3. "a" is a shortest leg in the smallest triangle,
so a=(15/2)/2=15/4
a+b=15
15/4 +b=15
b=15 -15/4=15*4/4 -15/4 = 45/4
b=45/4
