The value of the exterior angle is the sum of the angles opposite. This is an equilateral triangle, so all angles are equal to 60 degrees.

60 + 60 = 120

So angle DAB is 120 degrees.

Triangle DAB's angle measurement add up to 180 degrees

Since it is an equilateral triangle, each angle is the same measurements, or 60 degrees

Angle DAC is a straight line, and has a total measurement = 180 degrees

180 - 60 = 120

Angle DAB = 120 degrees

Hope this helps

Solve y = x^2 +11 <br> for x.

lisabon 2012 [21]

Answer:

x = ± $\sqrt{y-11}$

Step-by-step explanation:

Given

y = x² + 11 ( subtract 11 from both sides )

y - 11 = x² ( take the square root of both sides )

± $\sqrt{y-11}$ = $\sqrt{x^2}$ , hence

x = ± $\sqrt{y-11}$

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must

Nuetrik [128]

Let $w$ be the amount of water that evaporates. At the start, the solution in the tub consists of 2.5 gallons of salt (5% of 50 gallons). After $w$ gallons of water evaporates, we're left with a solution with total volume $50-w$ gallons, and 8% of this amount should be salt, or $0.08(50-w)$ gallons of salt. The amount of salt in the tank before and after evaporation remains unchanged, so
