Answer:
Step-by-step explanation:
Area of the rectangle = 33 inches sq
Area of a rectangle (formula) = l*b
let the width be x
length = 2 inches + 3x = 2+3x
Area of the rectangle = l*b = 2+3x + x
33 inches sq = 2+3x + x
33 in sq = 2+4x
33/2 = 4x
16.5/4 = x
x = 4.125
width= <u>4.125 inches</u>
length = 2+3x = 2+3(4.125) = <u>14.375</u>
<u></u>
(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
Answer:
AC ≈ 5.03
Step-by-step explanation:
We can solve the problem above using the trigonometric ratio, they are;
SOH CAH TOA
sin Ф = opposite / hypotenuse
cosФ= adjacent/ hypotenuse
tan Ф = opposite / adjacent
From the diagram above, in reference to angle B;
opposite =AC and adjacent =BC
Since we have opposite and adjacent, the best formula to use is
tanФ = opposite / adjacent
tan B = AC / BC
tan 40 = AC/ 6
Multiply both-side of the equation by 6
6× tan 40 = AC/ 6 × 6
At the right-hand side of the equation, 6 will cancel-out 6 leaving us with just AC
6×tan 40 = AC
5.034598 = AC
AC ≈ 5.03 to the nearest hundredths
