@Quizmania0 Draw a segment from A to B.
AB = 8 + 2 = 10 cm
Also, draw a segment from B to line A and perpendicular
to line A. A right angled triangle is formed.
Height of triangle = d
Hypotenuse = 10
Base = 6
By Pythagoras theorem
10^2 = d^2 + 6^2
d^2 = 100 - 36
d^2 =64
d = 8 cm
@Quizmania0 2x + 3x + 4x = 180
9x = 180
x = 20 degrees
Draw a line from m to n and perpendicular to both m and n.
A quadrilateral is formed. Angle m = angle n = 90
4x + 4y + 90 + 90 = 360
4(20) +4y + 180 = 360
4y = 360 - 260
4y = 100
y = 100/4
y = 25 degrees
