Question

Determine the value of ​

Answer 1

Answer:

2y + 10 =140 ,y=65°

Step-by-step explanation:

we know that this figure has a value of 360°.

hence, 50° + 40° + 130 ° + (2y + 10)° = 360°.

2y+10 =140°.

then y = 140- 10 /2.

y= 65°.

Answer 2

y = 65°

Step-by-step explanation:

we know that total circle angle is = 360 °

then

50°+40°+130°+(2y+10)° =360°

220° + (2y+10)° =360°

(2y+10)° = 360° - 220° = 140°

2y°+10° = 140°

2y° = 140° - 10° = 130°

y° = 130/2° = 65°

y° = 65°
