∠1 and ∠2 are complementary.
2 answers:
If two angles are complimentary then their sum would equal to 90 degree. i.e., x + 3x + 30 = 90 4x = 90 - 30 x = 60 / 4 x = 15In short, Your Answer would be Option A Hope this helps!
Answer:
The value of x is 15 .
Option (A) is correct.
Step-by-step explanation:
As given
∠1 and ∠2 are complementary.
i.e the sum of ∠1 and ∠2 is 90° .
Thus
∠1 + ∠2 = 90°
x° + (3x+30)° = 90°
x + 3x + 30 = 90
4x = 90-30
4x = 60
x = 15
Therefore the value of x is 15 .
Option (A) is correct.
