3. Find the angle complementary to the angle 80°25′. A. 180° B. 9°35′ C. 90° D. 99°35′

"Complementary" angles sum to 90°.

Since we are using minutes as well...

80°+d°+25'+m'=90° subtract 80° from both sides

d°+25'+m'=10° subtract 25' from both sides

d°+m'=9°+60'-25'

d°+m'=9°+35'

9°35'

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank

hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

$24 \times 12 \frac{1}{2} \times 12 \frac{3}{4}$

Change the numbers to improper fractions

$24 \times \frac{25}{2} \times \frac{51}{4}$

We cancel out to get

$3 \times 25 \times 51$

$3825$
