Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70

Answer:
B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.
Step-by-step explanation:
The slope of a perpendicular line is the opposite of the reciprocal of the slope of the original. Simon correctly computed the original line's slope to be -3/2. He correctly computed the reciprocal of that to be -2/3, but failed to recognize that the slope of the perpendicular line is the opposite of this, 2/3.
Simon's work is correct otherwise.
