I'd suggest getting a Texas Instruments TI-84 plus calculator or use des mos .com scientific
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
1/8 for the first one and second one is 23 times 6
Step-by-step explanation:
u can try putting the value one by one to check
or write
(12x +14 ) = ( 9x-×)
and solve it do u will get the answer
