Answer:

7000

Step-by-step explanation:

Recall the form of the difference of squares.

x^2 - y^2 = (x+y)(x-y)\\\\\\

Now let's apply it to your numbers:

85^2 - 15^2 = (85 + 15)(85 - 15)

Simplify:

(100)(70) = 7000

The sum of two angles is 180 and the angles have a ratio of 7:8. What is the number of degrees in the smaller angle??
Alona [7]

x - any unit in degrees

The ratio 7 : 8, therefeor the measures of the angles are 7x and 8x.

We know: the sum of those angles is 180°

Therefore we have the equation

7x + 8x = 180

15x = 180 |:15

x = 12

The smaller angle is 7x.

Your answer is 7 · 12° = 84°
