Supplementary angles measure 180°. Make an equation:
Subtract 28 to leave the variable in the parentheses alone:
Add the 2 x's together:
Your new equation is:
Divide both sides by 2 to leave the variable alone
The supplement measures 76°
Answer:
I think so
Step-by-step explanation:
Since we know that a negative times a negative equals a positive, we know that our answer is positive. Then follow the steps below.
Answer:
0 = 2x² - 23x + 45
Step-by-step explanation:
0 = (x - 5/2)(x - 9)
0 = x² - 5/2x - 9x + 45/2
0 = 2x² - 23x + 45
Answer:
m∠A = m∠2
Step-by-step explanation:
38° + m∠2 + 108° = 180°
The above statement is true because the sum of angles on a straight line is 180°
m∠A + 108° + 34° = 180°
This is also true because the sum of angles in a triangle is 180°.
m∠A = m∠2
This statement is false because 34°≠32°
m∠2 = 34°
This statement is true because:
m∠2 = 180-38-108=34°
