In the figure shown, which part of angles must be complementary?

1 answer:

4 0

Complementary angles are any 2 adjacent angles that make up 90°

knowing this, we see <COB is 90°, so now we just look for the 2 angles inside of it

<COD & <DOB

Two thirds of a number is no more than -10

Aliun [14]

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have

$\frac{2}{3}$ x≤-10

In order to cancel out the $\frac{2}{3}$ on the left and isolate x, we multiply both sides by $\frac{3}{2}$ (since $\frac{3}{2}$ · $\frac{2}{3}$ =1). Thus, we have

x≤-10· $\frac{3}{2}$ =-15

Therefore, x≤-15
