1 point) In AABC, a = 4.1 cm, b = 4.4 cm, and ZB = 64º.
Determine the measure of 2C to the nearest degree.
a. 55°
b. 61°
C. 57°
d. 590

Part A

Using substitution method, which means that substitute the value of y from first equation into the second equation, i.e.

7x – 8 = 5x – 2

This implies that;

2x = 6

x = 3

Now putting x = 3 in any equation, because both the equation will give the same value of y,

y = 5(3) – 2

y = 13

or

y = 7(3) – 8

y = 13

Part B

The point of intersection of the two equation graph is actually the solution of both equations. As the value of x = 3 and y = 13, then the point (x, y) = (3, 13) is the point of intersection of both equations.
