JK, KL, and LJ are all tangent to O. JA = 6, AL = 11, and CK = 13. Find the perimeter of
AJKL

(D) 60

Step-by-step explanation:

JA = JB , CK = BK , AL = CL

Thus, Perimeter = (JA+JB)+(CK+BK)+(AL+CL) = 2(JA + AL + CK) = 2(6+11+13) = 2(30) = 60

P.S :

Draw a straight line joining points J, O and C ; it becomes the symbol for the Deathly Hallows. LOL !

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
