The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.

So therefore, we can say it's 9:6, so DE is 6.

If you rotate the triangle so that the 6 is on the bottom, the two sides are both 6.2.

Because the two sides are equal the two angles at the bottom would also be equal. One is given as 61 degrees, so the other bottom angle is also 61 degrees.

The three inside angles of a triangle need to equal 180, so X would equal 180 minus the two bottom angles.

X = 180 - 61 - 61 = 58 degrees.

Step-by-step explanation:

the sum of n and 5 is (n + 5), then multiply by 3 gives

3(n + 5)

The result is at least 17 which means it must be greater than or equal to 17

3(n + 5) ≥ 17
