Answer:
Option (2). x = 20°
Step-by-step explanation:
In the figure attached,
ΔABC is an equilateral triangle.
By the property of equilateral triangle, all sides of the triangle are equal and measure of all angles of the triangle is 60°.
By this property,
m∠B = 60°
and y = 46 - 16 = 30
By applying Sine rule in ΔBCD,


sin(∠CBD) = 
= 0.6423
m∠CBD = 39.96
≈ 40°
m∠ABD = 60° - 40°
= 20°
Therefore, Option (2). 20° will be the answer.
If it's three or more, the probability is 100%.
However, I will assume that you intend to draw only two balls and that you don't replace the first ball in the bag for the second draw.
So you draw one ball. The probability that it's red is 8/14 = 4/7.
You draw again. The probability of getting a second red is 7 (red balls remains) / 13 (balls remaining).
Assuming that the results of the first and second draws are independent,the probability of drawing two red balls is therefore (4/7)*(7/13) = 4/13.
Now, suppose instead of a red on the first draw you got white. The probability of this is 6/14 = 3/7.
Given the first ball is white, the probability of drawing a second white is 5/13.
So the probability of drawing two whites is (3/7)*(5/13) = 15/91.
The outcomes of drawing two reds or two whites are independent of each other, so you can add the probabilities to get the probability of drawing two balls of the same colour, i.e.
4/13 + 15/91 = 43/91
If you prefer to express it as a percentage, it's approximately 47.25%.

x = 45°
Step-by-step explanation:
Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
