ANSWER : it is a right angle
Answer:
D Community property of addition
Step-by-step explanation:
Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.
4x + 4 = 6x - 14
Subtract 4x from both sides.
4 = 2x - 14
Add 14 to both sides.
18 = 2x
Divide both sides by 2.
x = 9.
Because we have a constant value of x, we can solve for BC.
BC = 2x + 7
2(9) + 7
18 + 7
25
<h3>The value of BC is 25.</h3>
Answer:
11.6in
Step-by-step explanation:
The correct statement which is true about angle 3 and 5 is, they are supplementary.
Step-by-step explanation:
- Two parallel lines are intersected by a third line so that angles 1 and 5 are congruent as they are supplementary.
- Supplementary Angles are Supplementary when the two angles are add up to 180 degrees.
- Examples of supplementary angles are 60° and 120°.
- Two lines are parallel when their slopes are equal. In order to see if the two lines are parallel, we must compare their slopes.
- A transversal is also known as a line segment, that intersects two or more other lines or also a line segments. When a transversal intersects parallel lines many angles are formed, which are known as congruent.
- If two parallel lines are intersected by a transversal, the corresponding angles are congruent.
- If two lines are intersected by a transversal, the corresponding angles are called as congruent i.e the lines are parallel.
