Explain Bot To find the two unknown angles, we need to set up an equation based on the information given.
We know that the sum of the two adjacent angles of a right angle is 90°. Thus, we can write the equation:
x + (x+30) = 90
Now, let's solve the equation to find the value of x:
2x + 30 = 90 (combining like terms)
2x = 90 - 30 (subtracting 30 from both sides)
2x = 60 (simplifying)
x = 60/2 (dividing both sides by 2)
x = 30
Now that we have the value of x, we can substitute it back into the equation to find the two unknown angles:
First angle: x° = 30°
Second angle: (x+30)° = 30° + 30° = 60°
Therefore, the two unknown angles are 30° and 60°. The answer is option (C) 30° and 60°.
