Increase 400litres by 20%
Sati [7]

Answer:

480 Litres

Step-by-step explanation:

Percentage increase = 20% × 400

New value =

400 + Percentage increase =

400 + (20% × 400) =

400 + 20% × 400 =

(1 + 20%) × 400 =

(100% + 20%) × 400 =

120% × 400 =

120 ÷ 100 × 400 =

120 × 400 ÷ 100 =

48,000 ÷ 100 =

480

Find the measures of the unknown angles in the triangle shown. Round it the nearest degree.
Fudgin [204]

Answer:

x = 49°

y = 41°

Step-by-step explanation:

Recall: SOH CAH TOA

✔️To find x, the trig function we would apply is Cos, which is:

Cos θ = Adjacent/Hypotenuse (CAH)

θ = x

Adjacent = 13

Hypotenuse = 20

Cos(x) = \frac{13}{20}

x = cos^{-1}(\frac{13}{20})

x = 49.4583981°

x = 49° (nearest degree)

✔️To find y, the trig function we would apply is Sin, which is:

Sin θ = Opposite/Hypotenuse (SOH)

θ = y

Opposite = 13

Hypotenuse = 20

Sin(y) = \frac{13}{20}

y = Sin^{-1}(\frac{13}{20})

y = 40.5416019°

y = 41° (nearest degree)
