Answers

Answer:

96 degrees

Step-by-step explanation:

The three angles in a triangle add up to 180 degrees. if angle one is 42 the the opposite angle is also 42. 42+42= 84 . Then 180-84 = 96 which would be the last remaining angle. Since the bottom and top triangle are the same the same is true for the bottom triangle.

I think it’s 96 degrees but I’m not to sure :)

Solve 4 + x > 6. Graph the solution. A)graph1 B)graph2 C)graph3 D) graph4

Answers

Given the inequality expression 4 + x > 6, we need to solve for x and graph the equivalent graph of the function;

Given

4 + x > 6

Subtract 4 from both sides of the inequality

4 + x - 4 > 6 - 4x > 6 - 4x > 2

Next is to graph the solution x > 2 on the number line.

Since the inequality sign is greater than sign, the line arrow will point towards the right of the number line and the circle will be an open circle.
