Answer:

4°

Step-by-step explanation:

All the angles in a triangle add together to equal 180°. We know there are three angles of 20° so let's subtract this.

20° × 3 = 60°

180° - 60° = 120°

Now well divide 120° up among the three angles.

120° ÷ 3 = 40°

Now we know the angles are 40° + 20°, but we need to find the value of x, so divide 40° by 10

40° ÷ 10 = 4°

x = 4°

Answer:4

Step-by-step explanation: Since you know this triangle is an equilateral, you know all angles are the same, so you should automatically multiply 10x+20 by 3. You would then get 30x+60. Since all triangle's total angle sum is 180, you know to set 30x+60 to 180.

At this point this might seem new, but this is where you isolate x. First you move the 60, but subtracting it from both sides. This gets you 30x=120.  You divide 30 on both sides and you finally get your answer: 4.

Answer:

Step-by-step explanation:

In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
