X=-10-7
X=-17
Answer:
∠a = <u>51°</u>
∠b = <u>48°</u>
∠c = <u>70°</u>
Step-by-step explanation:
∠c = 180° - 110° = <u>70°</u> (Angles on a straight line add up to 180°)
∠ADB = 180° - (110° + 19°) = <u>51°</u> (Angles on a triangle add up to 180°)
∴ ∠a = <u>51°</u> (Alternate angles are equal)
∠A = 180° - (51° + 62°) = <u>67°</u> (Angles on a triangle add up to 180°)
∠CAB = 67° - 19° = <u>48°</u>
∴ ∠b = <u>48°</u> (Alternate angles are equal)
2.1 X 10^10 = 21,000,000,000
0.3333333333... = 1/3
You can just say 0.3 repeating to say 0.33333...
