3x - 22
The given expression is simplified and cannot be further simplified.
What are the two angle measures of complementary angles expressed as 3x° and (2x−5)° ?(1 point) Responses 33° and 57° 33 degrees and 57 degrees 30° and 60° 30 degrees and 60 degrees 19° and 71° 19 degrees and 71 degrees 21° and 69°
To find the measure of complementary angles, we set up the equation:
3x + (2x - 5) = 90
Combining like terms:
5x - 5 = 90
Adding 5 to both sides:
5x = 95
Dividing by 5:
x = 19
Substituting x back into the expressions of the angles:
3x = 3 * 19 = 57°
2x - 5 = 2 * 19 - 5 = 38 - 5 = 33°
Therefore, the two angle measures are 57° and 33°.
3x + (2x - 5) = 90
Combining like terms:
5x - 5 = 90
Adding 5 to both sides:
5x = 95
Dividing by 5:
x = 19
Substituting x back into the expressions of the angles:
3x = 3 * 19 = 57°
2x - 5 = 2 * 19 - 5 = 38 - 5 = 33°
Therefore, the two angle measures are 57° and 33°.
Two angles are complementary. One angle has a measure of 40° and the other has a measure of (8x+2)° . What is the value of x ?(1 point) Responses 11 11 60 60 6 6 50
Since two angles are complementary, their sum should be equal to 90 degrees. Therefore, we can set up the equation:
40 + (8x + 2) = 90
Combine like terms:
8x + 42 = 90
Subtract 42 from both sides:
8x = 90 - 42
8x = 48
Divide both sides by 8:
x = 48/8
x = 6
Therefore, the value of x is 6.
40 + (8x + 2) = 90
Combine like terms:
8x + 42 = 90
Subtract 42 from both sides:
8x = 90 - 42
8x = 48
Divide both sides by 8:
x = 48/8
x = 6
Therefore, the value of x is 6.
