A two-column proof incorrectly proving that the three angles of ΔPQR add up to 180°
- Line YZ should be drawn parallel to PQ
<h3 /><h3>What are the lines parallel to each other</h3>
YZ is drawn parallel to PQ through the point R
<ZRP + <PRQ + <QRY = <ZRY
<ZRP = <RPQ [YZ // PQ]
<QRY = <PQR [YZ // PQ]
From the above,
<PQR + <RPQ + <PRQ = <ZRY =

Answer:
y is 3 since x is 4 then 4+3=7
Step-by-step explanation:
Answer:
First - y=-2x+3
Second - y=-7+3
Step-by-step explanation:
Answer:
jamie.
Step-by-step explanation:
if 1 mile equals 1.6 km, then terry walked 2.1875 miles (3.5 divided by 1.6)
2.1875(what terry walked) is less than 2.85 miles. (what jamie walked)
Answer:
x = -6
Step-by-step explanation:
In this equilateral triangle, all sides are congruent. Thus, all angles are generally congruent as well. This is a 60-60-60 triangle. So,
66 + x = 60
x = -6
