Start off by knowing that the two triangle are congruent. By knowing this you can turn the given numbers into fractions.
9/72 = 7/7x+7
then cross multiply, which equals
63x + 63 = 504
then solve this equation
63x = 441 - subtract 63 from both sides
x = 7 - divide by 63 from both sides
so your answer is x=7
I’m working it out give me like 5 minsss
C+3c is 4c and -4+9 is 5 so your answer is 4c+5
the answer is b 1/8 because 3/4 = 6/8 and 7/8-6/8=1/8
