When you square or cube a negative number is it still negative or does it become positive?

When you square a negative number, the result is positive.
(-4)^2 = (-4)ª(-4) = 16

When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64

Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.

A triangle has an angle that measures 95°. The other two angles are in a ratio of 3:14. What are the measures of those two angle
Marta_Voda [28]

Answer: 15° and 70°

Step-by-step explanation:

The sum of angles of a triangle is 180.

One of the angle is given to be 95°, this means that the sum of the remaining two angles will be ;

180 - 95 =  85°

The ratio of the two sides is given to be 3 : 14

Calculating the angles of each ,the angle with the ratio 3 will be

3/17 x 85 = 15°

The angle with the ratio 14 will be

14/17 x 85 = 70°

Therefore : the measures of the two angles are : 15° and 70°
