Question

Can somebody help me

Answer 1

Answer:

30°

Step-by-step explanation:

because this needs 180 angle so 150 (20+130)

180-150 equals 30

Answer 2

Answer:

30°

a full triangle is 180° so to find the missing angle you must add the two given angles (20°+130°) then take the answer away from 180° (180°-150°)

hence your answer is 30°
