Solve for y, z, x or t:

Rus_ich [418]

Answer:

Step-by-step explanation:

$if~it ~is ~y+\frac{y}{a} =b\\then~\frac{ay+y}{a} =b\\ay+y=ab\\ y(a+1)=ab\\ y=\frac{ab}{a+1} \\$

$z-a=\frac{z}{b} \\z-\frac{z}{b} =a\\ \frac{bz-z}{b} =a\\bz-z=ab\\z(b-1)=ab\\z=\frac{ab}{b-1}$

In AWXY, m_W = (10x +17), m_X = (2x – 9)", and m_Y = (3x + 7)º.<br> Find mZY

ella [17]

Answer:

$m\angle Y=40^\circ$

Step-by-step explanation:

Suppose we have a triangle WXY whose internal angles are:

$m\angle W = 10x+17$

$m\angle X=2x-9$

$m\angle Y=3x+7$

The sum of the measures of the angles must be 180°, thus:

$10x+17 + 2x-9+3x+7=180$

Simplifying:

15x + 15 = 180

Subtracting 15:

15x = 165

Dividing by 15:

x = 11

Thus, the measure of angle Y is

$m\angle Y=3x+7=3*11+7=33+7=40$

$\mathbf{m\angle Y=40^\circ}$

Step-by-step explanation:

Because what you want to do is add 260 to 182 then subtract from 587. I hope that helped! :)

What is the greatest number of obtuse angles a triangle can contain?

NikAS [45]

I think 1 because if you had 2 you'll end up with a shape that is greater than 180 degrees. Keep in mind obtuse angles a over 90 degrees. hope that helped
