Answer:
so 2a+3b=±13
Step-by-step explanation:
4a²+9b²=97
ab=6
2a+3b=?
by using formula
(a+b)²=a²+b²+2ab
(2a+3b)²=(2a)²+(3b)²+2(2a)(3b)
(2a+3b)²=4a²+9b²+12ab
putting values
(2a+3b)²=97+12(6)
(2a+3b)²=97+72
(2a+3b)²=169
taking square root on both sides
√(2a+3b)²=√169
2a+3b=±13
i hope it will help you
TO GET Y I WILL USE THE REASON SUM OF ANGLES IN A TRIANGLE:
y=12°
TO FIND X I WILL USE THE REQSON ALTERNATE ANGLES
x=13°
THEE ANGLES ARE INSIDE THE PARALLEL LINES :NOTE.
