Answer:The measure of angle RST is 120\°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m<RST=(6x+12)\° -----> equation A
m<RST=78\°+(3x-12)\° -----> equation B
equate equation A and equation B
(6x+12)\°=78\°+(3x-12)\°
Answer:
8.93
Step-by-step explanation:
I think it's 5 because 9 can go into 51 5 times with a reminder of 1 5 and 1
The length of the garden increases by 3 each time so the area goes up by 9 each time if the pattern doesn't change
