<u>In a parallelogram,</u>
⇒the angles adjacent to each other
⇒ are of the same measure
⇒so
∠A = ∠C
∠B = ∠D
<u>Let's solve</u>:
<u>Let's check</u>:
⇒ for all quadrilaterals like a parallelogram
⇒all the angle measures added up to 360, so:
<u>Thus</u>:
<u>Answer: w = 20 and z = 15</u>
Hope that helps!
1. there are 11 letters total and 1 m so 1:11
2. true
3. 10 total marbles. 2 black so 2/10 = 1/5
4. 3 x 3 x 5 = 45
5. 15 marbles so 6/15 black 4/15 blue = 8/75
6. 15 marbles so 5/15 red 5/15 x 5/15 = 1/9
7. 3/10 x 4/9 = 2/15
8. Drawing a club or a black card
9. Drawing a king or a queen
Your answer should be 57 .7 I think its right
