 Use the given information to find the value of x. Then, find the measure of angle ADC.
skad [1K]

Answer:

60degrees

Step-by-step explanation

To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;

x + <ADB + <CDB  = 360

x +150 + 150 = 360

x+ 300 = 360

x = 360 - 300

x = 60

Hence the value of x is 60degrees

At the 2012 Summer Olympic Games in London, in the Men's Shot Put qualifying round, the distances ranged from 17.58 meters to 21
chubhunter [2.5K]

Answer:

One standard deviation above the mean means a z-score of 1.0. If we put this into the calculator as normalcdf(1,999) = .159

15.9 percent of the athletes would have a distance greater than 20.56 meters.

Now multiply the number of athletes by the percent.

.159 * 40 = 6.346 = about 6 athletes

c. about 6 athletes

If you know the measure of the vertex angle of an isosceles triangle, how do you find out the measure of the base angles?
Irina-Kira [14]

Answer:

Step-by-step explanation:

An isosceles triangle has 2 sides that are the same length.  Let's say that our triangle has the 2 sides measuring the same and the base is a different length.  The vertex angle is the top angle.  By the definition of an isosceles triangle, since the 2 sides measure the same length, then the angles across from those sides have the same degree measure.  If we know the measure of the vertex angle, then we have

180 = vertex angle - base angle - base angle

but since the base angles are the same and we have 2 of them, then

180 = vertex angle - 2 base angles

For example, if the vertex angle measures 80 degrees, then 180 - 80 = 100.  That 100 has to be split in half for each of the base angles which are the same as each other.  So the vertex angle is 80 and each base is 50.
