<h3><u>Answer</u><u>:</u></h3>

40°

<h2><u>Step–</u><u>b</u><u>y</u><u>–</u><u>s</u><u>t</u><u>e</u><u>p</u><u> </u><u>explana</u><u>tion</u><u>:</u></h2>

Sum of interior angles in a triangle = 180

:. 2y + y + 10 + 50 = 180

→ 3y + 60 = 180

+60 crosses over, and we have:

3y = 180 — 60 → 3y = 120

At this juncture, we divide by the coefficient of y, as shown below↓

\frac{3y}{3}  =  \frac{120}{3}

Then, we have:

\frac{120}{3}  = 40

:. <u>4</u><u>0</u><u>°</u> is our final answer.

<h3><u>I</u><u> </u><u>hop</u><u>e</u><u> this</u><u> helps</u></h3>

An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
VikaD [51]

Answer:

It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

Step-by-step explanation:

An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of

ibuprofen left in the persons system

This means that in 2 hours time

400- 201.6= 198.4 mg was used up.

We need only 25 mg in the system

so 400- 25= 375 mg  time is needed

time          mg

2 hour      198.4

x                375

Using the cross product rule

x= 375*2/198.4

x= 3.780 hrs

Which means 3 hours and (0.78* 60)= 46.8 minutes.

It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour.
ira [324]

Answer:

  11 3/7 hours

Step-by-step explanation:

The shorter candle burns faster, so the candles will not be the same height (0) until the taller candle burns completely. At 0.7 in/h, that will take ...

  (8 in)/(0.7 in/h) = 80/7 h = 11 3/7 h
