If the measurement of one of the corners of an isosceles triangle base twice measuring the angle of his head, what measure the angle of the head?

The answer is 36 degrees

Step-by-step explanation:

Lets call the variables X= Base Angle and Y= Vertix Angle and  X=2Y

As Isosceles triangle theorem "If two sides of a triangle are congruent, then the angles opposite those sides are congruent" We asume that the X value of each base angle is the same and the sum of the three angles are equal to 180 degrees, so we have:

1)X+Y+X=180

2) We know that X=2Y so we replace them in the below formula

3) 2Y+Y+2Y=180

4) 5Y=180

5) Then we resolve the variable Y and divide the 180 degrees by 5 Y=180/5

6)Then we have that Y=36 Degrees

I hope that this answer finds you well

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
