Please help I don’t even know where to start! The angle of elevation from a person standing on the ground to a balloon in the air is 20°. The person walks 10 feet forward and the angle of elevation to the balloon is now 30°. How far away is the person from the balloon (after they walked ten feet)?

they are 30 ft away from the balloon

Step-by-step explanation:

every foot they move back equals one degree higher in the angle ten feet would equal 10 degrees.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
