The least common factor of 30, 45, and 10 is 5. 

30=2*3*5
45=3*3*5
10=2*5

By looking at the 3 prime factorizations, you can see that 5 is the biggest prime number that is present in all 3 prime factorizations.

Find The value of x, y and z​
Ratling [72]

Answer:

x = 18 ; y = 10 ; z = 102°

Step-by-step explanation:

The triangle in the pic is an isosceles triangle.

As it is an isosceles triangle , it's two sides will be equal .

=  > 3x - 42 = 12

=  > 3x = 42 + 12 = 54

=  > x = \frac{54}{3}  = 18

Also, both the base angles will be equal.

4y - 1 = 39

=  > 4y = 39 + 1 = 40

=  > y =  \frac{40}{4}  = 10

According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,

z + 39 + 39 = 180

=  > z + 78 = 180

=  > z = 180 - 78 = 102
