Answer:

-9

Step-by-step explanation:

If you have a problem that is plus a negative, you can get rid of the plus sign and move the minus sign to be the operation. In this problem, it would make the equation 6 - 15. We know that 6 + ? will equal 15 just as much as 6 - 15 = ?

6 + 9 = 15 therefore 6 - 15 must equal -9.

How can you determine if two triangle angles are similar using their angle measurements???? In ur own words !!

Andrej [43]

Answer:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
