the assumption here being that both lines JH and FH are tangent lines to the circle, if that's the case the external angle of 34° is the angle made by the equal tangents, meaning the triangle is an isosceles with twin sides.
In an isosceles triangle the twin sides make also twin angles, so the angles at J and F are twins, and they'd be 180° - 34° = 146° total, since they're twins, each one takes half, or 73°.
Answer:
5.779 x 10^-8 =0.00000005779
Step-by-step explanation:
The E-8 at the end means the number is multiplied by 10^-8.
So 5.779E-8=5.779 x 10^-8
A negative power means move the decimal place that many places to the left
So 5.779 x 10^-8 =0.00000005779

Answer:
a) System of equations will be: 
b) Number of adult tickets sold = 263
Number of students tickets sold = 237
Step-by-step explanation:
Let:
Number of adult tickets sold = x
Number of students tickets sold = y
a)
As Marc sold total 500 tickets, the expression will be: 
Student tickets cost $2 and adult tickets cost $5. Marc's sales totalled $1,789.
The expression will be: 
So, system of equations will be: 
b)
Solve the system to find value of x and y
Let:

Multiply equation 1 by 2 and subtract

We get value of x = 263
Now finding value of y by putting value of x in eq(1)

We get value of y = 237
Number of adult tickets sold = x = 263
Number of students tickets sold = y = 237
