Find the measure of angle A

48 degrees.

Step-by-step explanation:

you must set the two equations equal to 92 because 180-88 equals 92.

9x+3+8x+4=92.

now you have to bring over the 3 and 4, and subtract them from 92.

that gives you 9x+8x=85.

add 9 and 8 to get 17x.

now you need to divide to get x by itself, so divide both sides of the equation by 17.

17/17 cancels itself out leaving just x.

85/17 gives you 5.

therefore x=5.

you have to plug that back into your equation 9x+3, giving you 9(5)+3.

solve that in order, 9(5) = 45. then you have to add the 3, giving you your final answer of 48 degrees.

step-by-step explanation

2r= 2300

r =1150

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)
