Answer: x = 24° ,Option B
Step-by-step explanation: The angles are: (2x )°, 42°
→ The angles (2x)° and 42° are complements of 90°.
i.e. (2x)° + 42° = 90°
2x = 90-42=48°
2x=48°
x= 48/2 = 24°
∴x=24°
Answer:
B) 24 degrees
Explanation:
As this is a right angle with a total of 90 degrees you would first minus 42 from 90, which gives you 48. This now leaves you with just the 2x. As we know that 2x is 48 to work out x you would simply divide 48 by 2, which gives you 24.
1) Minus 42 from 90.
2) Divide 48 by 2.
