Answer:

C. Scalene triangle

Step-by-step explanation:

What I would do is add all of the angles to 180 and then solve for x.

6x + 10 + 7x + 15x + 2 = 180

28x + 12 = 180

28x = 168

x = 6

Then, plug in 6 for each expression to find each angle

6(6) + 10 = 46

7(6) = 42

15(6) + 2 = 92

Since none of the angles are equal and one of the angles is over 90 degrees, triangle GFH is a scalene triangle

Answer:

answer a

Step-by-step explanation:

$4d-6$ < $18$

Let's isolate $d$ on one side of the equation. Ignore the inequality for now. We'll deal with that later.

$4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6$

Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating $d$ , but if this confuses you, just do your math and keep the inequality there.

$d$ < $6$

On a number line, this would include every number less than $6$ , due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number greater than $6$ . But, how do we decide between answers a and c?
If a line has point at its beginning, $6$ , then that means that every number less than or equal to [ ≤ ] 6 is being shown, but our equation just says less than [ < ] 6, so answer a is our correct answer.
