Okay so you have to add up 15 and 11 and 4 so your answer is y=30
Answer:
First angle is 71, and the other is 19
A complementary angle is 90, so 71 + 19 = 90, while having a 52 degree difference
5/6 is an answer to your question
Answer:
x=4/3 or x=-7/2
Step-by-step explanation:
(3x-4)(2x+7)
Answer:
This is not a triangle
Step-by-step explanation:
If you use the triangle inequality theorem you can reach your answer.
The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle
