Question

find x,y,z in the following figure​

Answer 1

Answer:

x=125°, y=140°, z=30°

Step-by-step explanation:

ANGLE ON A LINE IS 180° --------(1)

40°+x°+25°=180° {from (1)}

65°+x°=180°

x°=125°. -------(2)

x°+25°+z°=180° {from (1)}

125°+25°+z°=180° { from (2)}

150°+z°=180°

z°=30°

40°+y°=180° {from (1)}

y°=140°

the values are

x=125°

y=140°

z=30°

Answer 2

Answer:

Explanation

• 40+X+25= 180 degree (linear pair angles are supplementary)
• 65+X=180
• X=180-65
• X=115
• angle z = angle 40 °(vertically opposite angles)
• z=40
• z+ y=180°(linear pair angles)
• 40 +y =180
• y=180-40
• y=140
