Sure:
90 year old parents : 60 year old children (had kids at 30; very reasonable)
60 year old parents : 40 year old children (had kids at 20; unlikly but possible)
45 year old parents : 30 year old children (had kids at 15; very unlikly but not impossible)
just do 6 times 7 on the second one!
Answer:
13 degrees
Step-by-step explanation:
mPQR=25 degrees , mRQT=11 degrees.
mPQT=PQR-RQT
MPQT=25-11=13 degrees

Explanation:
Here is one way to go about it.
<u>Statement</u> . . . . <u>Reason</u>
1. AD ≅ BC, AD║BC, E & F are midpoints of BC, AD . . . . given
2. (1/2)AD ≅ (1/2)BC . . . . multiplicative property of congruence (equality)
3. DF = (1/2)AD, BE = (1/2)BC . . . . definition of midpoint
4. DF ≅ BE . . . . substitution property of congruence
5. BE║DF . . . . segments of parallel lines are parallel
6. BEDF is a parallelogram . . . . BE ≅ DF, BE║DF, definition of parallelogram
Slope = (4 - 2)/(-6 - 2)= 2/-8 = -1/4
y = mx + b
2 = -1/4(2) + b
2 = -1/2 + b
b = 5/2
equation
y = -1/4x + 5/2
4y = -x + 10
x + 4y = 10
answer
<span>A) x+4y=10</span>
