Answer:

x = 26.4°

Step-by-step explanation:

Defence angle = x

Side length Opposite to reference angle = 4

Hypotenuse length = 9

Apply trigonometric ratio, SOH. Thus:

Sin x = Opp/Hyp

Sin x = 4/9

x = sin^{-1}(\frac{4}{9}

x = 26.3878° = 26.4° (nearest tenth)

Malachai is doing a 20 mile bike ride. he has cycled 11miles so far. what percentage of the total distance has he cycled?
iragen [17]
Ok, first you need to put 20 over 100: \frac{20}{100}

Now divide 100 by 20 and you will get 5

Every mile equals 5%

Take 5 and multiply it by 11 you should get 55%

Malachai has cycled 55% of the distance

Make R the subject of the formula , A equals to P( l+r/100)​
Mrrafil [7]

Answer:

r = 100(\frac{A}{P} - 1 )

Step-by-step explanation:

Given

A = P(1 + \frac{r}{100} ) ← divide both sides by P

\frac{A}{P} = 1 + \frac{r}{100} ( subtract 1 from both sides )

\frac{P}{A} - 1 = \frac{r}{100} ( multiply both sides by 100 )

100 ( \frac{P}{A} - 1) = r
