Answer:
x = 2
Step-by-step explanation:
Given a line parallel to a side of a triangle and intersecting the other 2 sides then it divides those sides proportionally, that is
= ( cross- multiply )
6x = 4(x + 1)
6x = 4x + 4 ( subtract 4x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Answer: D
Step-by-step explanation:
A. Not A because more students answered anything but none
B. Not B because 20 + 30 = 50, 50 is more than 40
C. Not C because there are 10 students above none
D. D is the answer because we have no info abt how much people are being paid
Sum of angles of a triangle = 180°
91 + 10x - 4 + 8x +3 = 180
18x + 90 = 180
18x = 90
x = 5°
