Answer:
m∠B = 95°
Scalene
Step-by-step explanation:
by definition, internal angles in a triangle must add up to 180°
in this case,
∠A + ∠B + ∠C = 180°
we are given ∠C = 55° and ∠A = 30°
30° + ∠B + 55° = 180°
∠B = 180 - 55 - 30 = 95° (Answer)
We can see that all 3 angles of the triangle are different. And hence we can conclude that all 3 sides of the triangle are different length (i.e it is not equilateral or isosceles). Hence it is a scalene triangle.
The answer would be A.
It is reflected across the x-axis means that point E' will be at (-3, -2) and point F' would be at (-1,-2)
the length of the line would be the same regardless of anyway you translate, rotate, or reflect it. Only if you dilate it, then an object's size can change.
Hope that helps :)
