Answer:
x=11∘
Step-by-step explanation:
So to do this, you need to understand that the sum of angles in a triangle is 180∘. If we understand this, we can add up all of the angles in ΔGHI and make the sum 180∘ to get an algebraic equation:
10x+9+3x+13+x+4=180 - Combine like terms
14x+26=180 - subtract 26 on both sides
14x = 154 - divide by 14 on both sides
x=11∘

Question 2(Multiple Choice Worth 5 points) (06.07A MC) The figure shows the location of 3 points around a lake. The length of the lake, BC, is also shown. (Figure is not drawn to scale.) A picture of a right triangle ABC with right angle at B is shown. The length of the side AC is labeled as 9 miles. The length BC of the triangle is labeled as 6 miles. This length BC is also the length of an irregular gray shaded shape. Which of the following options is closest to the distance (in miles) between points A and B? 6.71 miles 7.35 miles 8.66 miles 10.82 miles
answer - 6.71

answer - i need the triangles the be able to answer
The answer to this question is 6
Since the board is in inches, she can lay the board on the side of the rug. after she finds how many inches the rug is, Lyza can convert the inches into feet by dividing the amount of inches by 12.
Next time you post a question, break it up into a couple of questions. If you don't want to do that use paragraphs and finally, if that doesn't suit you add more points -- Please. No offense intended. the please is genuine.
1. A triangle = 180o. If one is 90, the other 2 will be a total of 90o
Answer C: <<<====
2. A looks like the correct answer. 30 + 100 = 130 ; 180 - 130 = 50
3. You need a diagram to get the third one.
