check the picture below.

bearing in mind that there are 60 minutes in 1 degree, then 16°18' will be 16.3° and likewise 48°51' will be 48.85° if we convert those to degrees only.

$\bf y=\cfrac{200}{tan(48.85^o)}~\hspace{10em}x=\cfrac{200}{tan(16.3^o)}-y \\\\\\ x=\cfrac{200}{tan(16.3^o)}-\cfrac{200}{tan(48.85^o)}\implies x\approx 683.95 - 174.78\implies x\approx 509.17$

A triangle contains angles mesuring 28 degrees and 37 degrees. How many degrees is the third angle?

Orlov [11]

Answer:

115°

Step-by-step explanation:

We know that:

Angles ∠A and ∠B are 28° and 37°.

We don't know:

Angle ∠C's angle

So, we do this:

Add the 180°
Solve the equation 180 - 28 - 37

Solve:

180 - 28
= 152 - 37
= 115.

Angle ∠C is 115°.

If Cody is draining his hot tub which holds 1,400 gallons of water at a rate of 27 gallons a minute, what impact will it have on

inessss [21]

Facts:

- tub has 1400 gallons

- draining at 27 gallons/minute

How much water will be left after 18 minutes?

We know that after 1 minute, there will be 27 gallons less.

So after 18 minutes, there must be 18 times less water.

27 x 18 = 486

This is how much water was lost in 18 min

So to find out how much he had left after 486 is subtracted.

Therefore, the answer is A) -486 gallons
