Triangle ABC is a right triangle and cos(22.6o)=b/13. Solve for b and round to the nearest whole number. Which equation correctly uses the value of b to solve for a? tan(22.6o) = a/13 tan(22.6o) = 13/a tan(22.6o) = a/12tan(22.6o) =12/a

cos22.6° = b/13

b ≈ 12

Step-by-step explanation:

Step 1: Multiply both sides by 13

13cos22.6° = b

Step 2: Plug into calc

You should get 12.0017 as your answer.

if x decreases by 4 then y increases by 10

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
