The data observed from the triangle are given below.
Statement Reason
Given
Draw 
so that M is the midpoint of QR. Two points determine a line
Definition of midpoint
Reflexive property of congruence
SSS congruence postulate
CPCTC
SSS means side-side-side
CPCTC means corresponding parts of the congruence triangle are congruent.
Hence the given triangle is SSS congruence postulate
Answer:
one hundred and twenty-six thousand five hundred and forty-seven
Step-by-step explanation:
F(r) = 60 - 2/3r r = 12
Substitute r for 12
f(12) = 60 - 2/3(12) 12 * 2/3 = 8
f(12) = 60 - 8
f(12) = <u /><em><u>52</u></em><em><u /></em>
52 is your answer

Since 980÷2=490÷2=245÷5=49÷7=7÷7=1
980=2×2×5×7×7
the greatest perfect square will be
7*2*7*2
14*14=196
