Answer:
It is given that, AB and P Q are parallel lines.Line segment CR and D S, intersect the two lines.
Line segment CR and D S ,are Transversal to parallel lines, AB and P Q.
⇒∠C + ∠ R=180°
⇒90°+∠ R=180°
∠ R=180°-90°
∠R=90°
Similarly, ∠S=90°
→∠R+∠S=90°+90°=180°
As, sum of interior angles on the same side of transversal is 180°, so lines are Parallel.
→CR║DS
Also, AB║CD→CD║RS.
If in a Quadrilateral, opposite sides are parallel, then it is a Parallelogram,and also each interior angle has measure 90°, so it is a Rectangle.
In a rectangle opposite sides are equal.
Step-by-step explanation:
Step-by-step explanation:
63+36+X = 180 (interior angles of a triangle equal 180)
X = 180-99
X= 81
X+Z= 180(angles on a straight line adds up to 180)
81+y= 180
Z=180-81
Z =99
13+Z+Y=180
13+99+Y=180
Y=180-112
Y=68

Step-by-step explanation:
So basically all you have to do is substitute x = -4 into the equation, so it would be:
hope that makes sense!
