To solve this problem, you have to know that the measure of all the angles of a triangle is equal to 180 degrees.
Let's add each angle together and set them equal to 180 degrees.
180 degrees = 3x + 2x + 1 + x + 5
Combine like terms
180 degrees = 6x + 6
Subtract 6 from both sides
174 degrees = 6x
Divide both sides by 6
29 = x
We know that angle A = 3x = 3(29) = 87 degrees.
Answer:
D = 0
Step-by-step explanation:
D = b^2 - 4ac =
= 6^2 - (4*1*9) =
= 36 - 36 = 0
The factors of 83 our 1 and 83. So does that make it a prime number? Answer: Yes
