Question

please solve 7 number its urgent.​

Answer 1

Answer:

Step-by-step explanation:

y = 120 degrees

y = 50 degrees

x = 20 degrees

Answer 2

Answer:

ANSWER:-

7 i) \_DAB=60°[GIVEN]

\_DAB=\_ABC [ALTERNATE ANGLES ARE EQUAL]

\_ ABC= 60°

\_ABC=\_ACB [ WE KNOW THAT IN A TRIANGLE TWO OPPOSITE ANGLES ARE EQUAL TO EACH OTHER]

\_ACB = 60°

THAT IS \_ Y = 60°

NOW,

_____________________________________________

Step-by-step explanation:

WE GOT \_ACB AND \_ABC

SO, WE KNOW SUM OF 3 ANGLE OF A TRIANGLE IS 180°

\_ ACB +\_ABC +\_CAB=180°

=>60°+60°+\_X = 180°

=> \_X + 120°=180°

=> \_X=180°-120°

=> \_X=60°

_____________________________________________

7 ii) \_BAC=55° [GIVEN]

\_BAC=\_ABC[ ALTERNATIVE ANGLES ARE EQUAL]

\_ABC=55°

\_ Y=55°

\_X +\_Y= 180°

\_X + 55°= 180°

\_X = 180°-55°

\_X=125°
