Answer:
15
Step-by-step explanation:
(3×3-3)^2 :3 +3 =
(9 - 3) ^2 :3 +3 =
6 ^2 :3 +3 =
36 :3 +3 =
12 +3 =
12?
4(-3 + -2d) = 12
(-3 * 4 + -2d * 4) = 12
(-12 + -8d) = 12
-12 + -8d = 12
-12 + 12 + -8d = 12 + 12
-12 + 12 = 0
0 + -8d = 12 + 12
-8d = 12 + 12
12 + 12 = 24
-8d = 24
d = -3
Lenght: 34.51 mm
Area: 1035.33 mm^2
let x be the unknown sidelength
tan(41) = 30/x
x = 34.51
multiply by 30 to get area
Step-by-step explanation: 50 x. 10
