Divide -10 in 15 = -0.666666666
Answer: b. 125
Step-by-step explanation:
Find the square roots of each, and if the square root is a decimal, it is not a perfect square.
Square root of 81: 9
Square root of 49: 7
Square root of 100: 10
That leaves 125.

Answer:
a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship
b. To insert between neighboring points or estimate by taking an average of known values - interpolate
c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship
The definition of a right triangle is a triangle with a right angle. Therefore one of the angles of the triangle is 90 degrees. The second angle is 61 degrees. The angles of a triangle sum to 180 degrees.
90 + 61 = 151
180 (sum of angle degrees in a triangle) – 151 (sum of 2 of angles of the triangle) = 29 (third angle measure)
Therefore the missing angle is 29 degrees
Hope this helps you! :)
