Answer:

71°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle

m<x + m<y = m<z

4n - 18 + n + 9 = 151 - 5n

5n - 9 = 151 - 5n add like terms

10n = 160

n = 16

Since m<z = 151 - 5n we replace n with 16 and 151 - 5×16 = 71

Answer:

A. 71

Step-by-step explanation:

x + y = z

4n - 18 + n + 9 = 151 - 5n

5n - 9 = 151 - 5n

10n = 160

n = 16

Z = 151 - 5(16) = 71

What would happen to the sum of a geometric series if the ratio was 1?

dusya [7]

If the ratio of Geometric is 1.

The value of each term is the same.

E.g a, a, a, a, a, ....

So the sum of first n terms would be n multiplied by each term = na

(z-24) divided by 8+2

hjlf

Answer:

z=-24

Step-by-step explanation:

(z-24)/8+2

(z-24)/10

((z-24)/10)10 Multiply both sides by 10

10(z-24) Distribute

10z-240 Divide both sides by 10

z=-24

I'm not sure how to do these equations

Gennadij [26K]

$\frac{x^2+4x+3}{x^2-4x-21} = \frac{(x+3)(x+1)}{(x+3)(x-7)} = \frac{x+1}{x-7}$
$\frac{x^2+10x+16}{x^2+13x+40} = \frac{(x+8)(x+2)}{(x+8)(x+5)} = \frac{x+2}{x+5}$
