Enter your answer and show all the steps that you use to solve this problem in the space provided. Find the values of x and y.
satela [25.4K]

Answer : The value of x and y is, 90^o and 43^oC

Step-by-step explanation :

First we have to calculate the angle B.

As we know that,

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, \angle B=\angle C

Given : \angle C=47^o

\angle B=\angle C=47^o

\angle B=47^o

Now have to calculate the angle A.

As we know that the sum of interior angles of a triangle is equal to 180^o.

\angle A+\angle B+\angle C=180^o

\angle A+47^o+47^o=180^o

\angle A+94^o=180^o

\angle A=180^o-94^o

\angle A=86^o

Now we have to determine the angle y.

As we know that, line AD is an angle bisector. That means, it divides into two equal angles. So,

\angle y=\frac{\angle A}{2}

\angle y=\frac{86^o}{2}

\angle y=43^o

Now we have to determine the angle x.

As we know that the sum of interior angles of a triangle is equal to 180^o.

\angle y+\angle B+\angle x=180^o

43^oc+47^o+\angle x=180^o

\angle x+90^o=180^o

\angle x=180^o-90^o

\angle x=90^o

Thus, the value of x and y is, 90^o and 43^oC

A laundry basket contains 10 socks, of which 2 are red. What is the probability that a randomly selected sock will be red? Write
algol13

Answer:

you get a pair of red socks. There are 10 socks in the drawer, and 2 are red. Therefore the probability that the first one will be red is 2/10 = 1/5.

An object is launched from a platform. It's height (in meters), x seconds after the launch, is modeled by: h(x)=-5(x-4)^2+180. W
Kipish [7]

The height of the object at the time of launch is 100 meters.

To find this, we simply have to put 0 in for x, as this is when there has been no time (at launch)

h(x)=-5(x-4)^2+180

h(0)=-5(0-4)^2+180

h(0)=-5(-4)^2+180

h(0)=-5(16)+180

h(0)=-80+180

h(0) = 100
