B is the answer have a good day
Answer:
12 sides
Step-by-step explanation:
If the three equal angles add to 90, this means each of those angles must by 30 degrees.
Next, we can use the theorem that the sum of the exterior angles adds to 360 (this is true for any polygon). So, as the exterior angles are all equal to 30, we just work out 360 ÷ 30 = 12.
So the polygon has 12 angles, and therefore 12 sides also.
The kind of probability is being used when one calculates the probability that a randomly selected adult who works from home and has a bachelor's degree or higher is <em>relative frequency.</em> This probability is based on actual measurements, like a survey. Using this method will enable us to calculate for the probability of each variable occurring, or a combination of two or more variables with respect to the number of trials in the sample.
Multiply each throughout!
=x^2+6x+8x+48
then arrange accordingly
x^2+14x+48
remember that in quadratic equation that you should have a squared (a) variable and a coefficient(b) and just a raw value (c)
∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
