Answer:

46.19 feets

Step-by-step explanation:

Using Pythagoras rule :

Sin θ = opposite / hypotenus

Let length of string = s

Sin 60 = 40 / s

s * 0.8660254 = 40

s = 40 / 0.8660254

s = 46.188021 feets

s = 46.19 feets

A road is inclined at an angle of 5°. After
Scorpion4ik [409]

Answer:

464 feet

Step-by-step explanation:

<em>The Sine of the angle of inclination gives the increase in altitude.</em>

<em>This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e</em>

Sin Ф = Opposite  ÷ Hypotenuse

Sin 5° = O ÷ 5328

0·08716 = O ÷ 5328

<em>Make </em>O<em> the subject and multiply every fraction by </em>5328

(0·08716/1 × 5328)= (O/5328 × 5328)

464·388 = O

∴ The increase in altitude is 464·388 feet

<em>This is supposed to be to the nearest foot so we round off</em>

464·388 becomes 464 feet

Pls help me with this math!
Neko [114]

Answer:

x = 50.60 cm

Step-by-step explanation:

Given triangles ΔMAB and ΔMNP are smilar accordingly their corresponding sides are proportional.

But first we will determine the size of the side MA:

MA = MN - AN = 46.2 - 14 = 32.2 cm

Now we will make proportion:

MN : MA = MP : MB  =>  46.2 : 32.2 = 72.6 : x

When we multiply external and internal members we get:

46.2 x = 72.6 · 32.2 => x = 72.6 · 32.2 / 46.2 = 2337.72 / 46.2 = 50.60 cm

x = 50.60 cm

God with you!!!
