I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
We know that the measure of arc AC = 92 degrees, and x and y are both inscribed angles of this arc, which means that they will have 1/2 of its measure.
Therefore, x = 1/2 (92) = 46 degrees and y = 1/2 (92) = 46 degrees
x = 46, y = 46 is your answer, or the first option
Answer:
AC and DF
Step-by-step explanation:
We can see that the triangles have a scale factor of 3.
1 * 3 = 3 (AB and DE)
2 * 3 = 6 (BC and EF)
However...
2 * 3 = 6 not 7 (AC and DF)
Scalene triangle
because all sides are of a different length
