Given that the measure of ∠x is 120°, and the measure of ∠y is 60°, find the measure of ∠z.

Alexxx [7]

Answer:

60 degrees

Step-by-step explanation:

angle y is vertically opposite to angle a, (we can call it.)

angle x is supplementary to the other angle inside the triangle, which we can call angle b.

so, angle a is 60 degrees, as vertically opposite angles are equal

angle b is 60 degrees as supplementary angles = 180

based of the sum of angles in a triangle is 180 theorem;

60+60+unknown= 180

so unknown is 60 degrees

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in the simplest form 15,1

Tatiana [17]

Step-by-step explanation:

the sequence is arithmetic due to the common difference that is equal

d=11-15=7-11=-4

a(n) = a1 +(n-1)d

a1=15

Then :

a(n) = 15+(n-1)-4
