Answer:
77.5 degrees and 102.5 degrees
Step-by-step explanation:
Given that : one angle is25 degrees greater than another. Let the two angles be represented by a and b. Since one angle is 25 degreess greater than another, then:
b = a + 25 degrees
But;
a + b = 180 degrees (sum of angles on a straight line)
a + a + 25 degrees = 180 degrees
2a = 180 degrees - 25 degrees
a = 77.5 degrees
b = 77.5 degrees + 25 degrees = 102.5 degrees
Therefore the measures of all angles formed by the lines is either 77.5 degrees or 102.5 degrees.
Answer:
r = 3
Step-by-step explanation:
− 3 ( 6 r + 2 ) + 5 ( r + 1 ) = − 40
- 18r - 6 + 5 ( r + 1 ) = - 40
- 18r - 6 + 5r + 5 = - 40
-13r - 1 = - 40
-13r = - 39
r = 3
If you want the expression, the expression would be:
3.5x+50
