Question 1187126: The triangle is 30-60-90
12ft base next to 60 degrees ( I wish I could attach an image)
1. Use special right triangles to help find the length of segment XY. What is the exact height of triangle XYZ?
2. What is the exact area of triangle XYZ? Leave your answer in radical terms. I came up with 6 square 3
3. What is the area of triangle XYZ to the nearest tenth of a square in? \( 1350^2 I think) I'm really trying to make sure but I'm confused

Question 1187307: What is the missing side length in the image? Tell if the side lengths form a Pythagorean triple. Explain.
Here is a link to the image: https://imgur.com/a/E3FiPtQ
For this problem I got 15 as the missing side length; and yes the side lengths form a Pythagorean triple. Explanation: The set (15, 20, 25), which gives the side lengths of this triangle, is the Pythagorean triple (3, 4, 5) multiplied by 5. Would my answer to this be correct?

Question 1187655: Explain why ∆ABC ~ ∆DBE and then find BC. Would my answer be correct?
Here is a link to the image: https://imgur.com/a/YOInNLJ
This is my answer:
AC \\ DE by the Converse of the Corresponding Angles Postulate. ∠A ≅ ∠BDE by the Corresponding Angles Postulate. ∆ABC ~ ∆DBE by AA Similarity. Corresponding sides are proportional, so BC = 42.

Question 1187795: One side of triangle has an equation of 2x - 5 next side has 3x + 20 and the last side has 2x. I need to solve for x
My answers: x = 3
I'm having trouble because i know all sides are supposed to equal 180 and when I replaced x with 3 for all sides it didn't add up to 180
