Question

The degree

measure


three
angles of a triangles are x,y
and z. If z=x+y/2 then

find them.​

Answer 1

Answer:

Given x,y and z are three angles of a triangle.

and

z = \frac{x+y}{2}z=2x+y

2z = x+y2z=x+y ---(1)

We know that,

x+y+z=180°----(2)

/* Angle sum property */

=> 2z+z = 180° /* from (1)*/

=> 3z = 180°

=> z = 180°/3

=> z = 60°

Therefore,

z = 60°

Answer 2

Answer:

${60}^{o }$

each Z, y and x

Step-by-step explanation:

$z = \frac{x + y}{2} \\ = >2 z = x + y \\ take \: x \: and \: y \:is \: equal \: to \: {60}^{o} \\ = > z = \frac{120}{2} \\ = > z = {60}^{o}$
