Answer:
The measures of the angles are 65° and 80°
Step-by-step explanation:
One of the angles is 35°
We know that the other two angles have a difference of 15°
With this knowledge we can write an equation.
2x symbolizes the two angles
+15 symbolizes the difference between the two angles
145 = 2x + 15
145 - 15 = 130
2x = 130
x = 65
65 is the size of one of the angles.
Next, we add 15 to 65 and we get 80
80 is our second angle
Answer:
The first one isn't the second one is.
Step-by-step explanation:
In the first one, they have to be equal because they're corresponding angles so m and n are parallel.
In the second one, m<2 and m<3 would be supplementary and add up to 180 degrees if the lines were parallel and since they don't add up to 180, the lines are not parallel.

Answer:
x = 30°
2x = 60°
3x = 90°
Step-by-step explanation:
GBF = CBD (opposite angle)
; 2x+x+3x = 180° (Size of straight angle)
6x = 180
x = 180÷6
x = 30°
substitution x in 2x ; 2×30 = 60°
substitution x in 3x ; 3×30 = 90°
