Answer:
Step-by-step explanation:
I gave you the answer earlier too!
for more info !
Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points
which means
2x-4 = 1/2×21
thus, 2(2x-4) =21
=> 4x-8 = 21
4x = 29
~183.78
A = pi 9² ≈254.47
260/360=13/18
254.47/18×13≈183.78
Z €{9, i can right a fraction but on top is 9 below is 4}
