Answer:
38) Angle 2 = 32°; angle 1 = 32°; angle 3 = 110°
39) Angle 3 = 81°; Angle 2 = 28°; angle 1 = 71°
Step-by-step explanation:
38) angle 2 = 180 - (110 + 38)
This is because sum of angles in a triangle is equal to 180°. Thus;
Angle 2 = 32°
Angle 1 = 38° due to the postulate that alternate interior angles are equal
Angle 3 = 110° due to corresponding angles postulate
39) Angle 3 = 81° due to the postulate that alternate interior angles are equal
Angle 2 = 28° due to the postulate that alternate interior angles are equal
Angle 1 = 180 - (81 + 28) = 71° due to the fact that angles in a triangle sum up to 180°
I have solved the answer in the pic below, hope it helpss!!!!
Answer:
Line 3
Step-by-step explanation:
The problem's lines are:
Line 1. 5(x - 5) = 15
Line 2. 5x - 25 = 15
Line 3. 5x - 25 = 15 - 25
Line 4. 5x = -10
Line 5. 5x/5 = -10/5
Line 6. x = -2
The first error is in Line 3, where 25 was subtracted from just the right side, and where 25 should have been added to both sides instead.
