ΔABC has the following angle measures: A = 40 degrees, B = 60 degrees, and C = 80 degrees. The triangle is reflected across the

x-axis to obtain ΔA’B’C’. What is the measure, in degrees, of angle B' ?

Answer:

60 degrees.

Step-by-step explanation:

A reflection does not alter the size of the angles of the triangle so B = 60 degrees.

Explain how you can determine that the following system has one unique solution – without actually solving the system.

MakcuM [25]

Answer:

Step-by-step explanation:

Well, first you'd have to get the equations in slope-intercept form in order to make it easier for you to see it in the bigger picture. 2x+y=4 would be y= 2x-4, and the other equation would be y= x-3. If you were to solve it, there would be one solution since the y's cancel out. If you graphed it, there would be a point of intersection, unlike when the lines are parallel if there's 0 solutions or only one line's there if there's infinitely many solutions.

Use the Law of Sines. Find m2c to the nearest tenth.

seropon [69]

Answer:

Step-by-step explanation:

Set up the Law of Sines as follows:

$\frac{sinC}{58}=\frac{sin30}{35}$ and

$sinC=\frac{58sin30}{35}$ and

sinC = .8285714286 so

C = 56.0°
