9. Angle LSM and Angle 2 are pair of vertical opposite angles which are equal.

10. Angle forming vertical pair with Angle 1 is Angle LSO (Angle 3).

3x+3y=6 and 5x-6y=15

Anna71 [15]

Multiply first equaton by 2 and add to the other equation

6x+6y=12
5x-6y=15 +
11x+0y=27

11x=27
divide both sides by 11
x=27/11

sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus 2 and 5/11 both sides
y=-5/11

x=27/11
y=-5/11
(27/11,-5/11)

In a parallelogram, if the measure of y is 32 degrees what is the measure of w

alekssr [168]

Talking about a parallelogram, we know that:
opposite sides and angles are congruent
in the picture below:
∠A = ∠C
AD = BC
if one angle is right, then the rest are right as well (making it a rectangle/square)
The consecutive angles are supplementary (meaning they add up to 180)
A + D = 180°

If y and w are consecutive angles, then
w = 180 - 32
=148°
If they are opposite angles, w = 32° (congruent angles)
