Answer:
Yes it is correct because the corresponding lines are all together.
sorry if i was wrong this is how i did mine and got 100% on the question.
The main thing is when we have a transversal across parallel lines we generate a bunch of angles, which they've numbered 1 through 8. Some are the same angles, some are supplementary angles, which means they add up to 180°. So really for math you just need to know whether it's the same or the supplement, which is pretty obvious from the figure.
But here they want us to match the names. I can never remember them but we're given a menu.
∠2 and ∠5 are alternate interior angles. Alternate means on opposite sides of the traversal. Interior means between the parallel lines. Say the mantra: Alternate interior angles are congruent.
∠3 and ∠5 are none of the above. They're supplements but I don't think they have a name. Usually we proceed in two steps. ∠3 and ∠1 are a <em>linear pair</em> so supplementary. ∠1 and ∠5 are <em>corresponding angles </em>so are congruent.
∠3 and ∠8 are alternate exterior angles. Exterior means outside the parallel lines. Alternate exterior angles are congruent.
∠4 and ∠7 are alternate interior angles so congruent.
∠4 and ∠8 are corresponding angles so congruent.
They didn't give an example, but ∠3 and ∠4 are <em>vertical angles</em>, and vertical angles are congruent.
Answer:
V≈113.1
Step-by-step explanation:
The value of x is 91.2 degrees if Larry is reroofing his house. each side of the roof measures 14 feet from the eave to the ridge.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a triangle shown in the picture:
We can find the angle using cos law:
After solving:
x = 91.2 degree
Thus, the value of x is 91.2 degrees if Larry is reroofing his house. each side of the roof measures 14 feet from the eave to the ridge.
