Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.
So
5<em>x</em> = <em>x</em> + 12
4<em>x</em> = 12
<em>x</em> = 3
→ PQ = 5<em>x</em> = 15
and
12<em>z </em>° + 6<em>z</em> ° = 180°
18<em>z</em> ° = 180°
<em>z</em> = 180/18 = 10
→ m∠<em>S</em> = 12•10° = 120°
Answer: a correct me if I’m wrong
Step-by-step explanation:
1-2:<span>Yes. But not all parallelograms are squares</span><span>
3-false ! are </span><span>plane figures.
4-True ! </span>Every square is a rhombus<span>
5-False , </span><span>every rhombus is not a square.
6-7 : </span>Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
Answer:
A1 = 18
A(n) = A (n-1) -2
Step-by-step explanation:
N represents the number in a sequence and the difference in the sequence is -2 since each time the number is listed in the sequence it is divide by 2.
