Question

please help me tommorow is exam​

Answer 1

Step-by-step explanation:

In the given figure we have-

AB || CD || RS, ANGLE ABG = 110°, ANGLE GCD = 100° SO WE HAVE TO FIND ANGLE BGC

NOW , ANGLE ABG + ANGLE RGB = 180° CO - INTERIOR ANGLES

= SO ANGLE RGB = 180-110 = 70°

similarly angle dcg + angle sgc = 180° co interior angles

so angle sgc = 80°

now angle bgr + angle BGC + sgc = 180°

= straight angle property

= 70° + x° + 80° = 180° so

x = 30° ( by solving)

Answer 2

Answer:

(3) 30°

Step-by-step explanation:

Here, (110°-x°) + x° + (100°-x°) = 180° (Linear pair)

=> 210° - x° = 180°

=> x° = 30°

So, (3) 30°
