HELP PLS I NEED TO TURN IT IN MONDAY!

Mathematics

Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.

\frac{Lap}{Time}

Put the amount of laps on the top and the time(minutes) at the bottom.

\frac{3}{2.5} = \frac{20}{x}

Cross multiply:

20 \times 2.5 = 50

Divide by 3:

50 \div 3 = 16 \frac{2}{3} \rightarrow 16.67

It would take Terri 16 \frac{2}{3} OR 16.67 minutes to run 20 laps.

Answer:

  ∠CAB = 28°

  ∠DAC = 64°

Step-by-step explanation:

What you do in each case is make use of the relationships you know about angles in a triangle and around parallel lines. You can also use the relationships you know about diagonals in a rectangle, and the triangles they create.

<u>Left</u>

Take advantage of the fact that ∆AEB is isosceles, so the angles at A and B in that triangle are the same. If we call that angle measure x, then we have the sum of angles in that triangle is ...

  x + x + ∠AEB = 180°

  2x = 180° -124° = 56°

  x = 28°

The measure of angle CAB is 28°.

__

<u>Right</u>

Sides AD and BC are parallel, so diagonal AC can be considered a transversal. The two angles we're concerned with are alternate interior angles, so are congruent.

  ∠BCA = ∠DAC = 64°

The measure of angle DAC is 64°.

(Another way to look at this is that triangles BCE and DAE are congruent isosceles triangles, so corresponding angles are congruent.)
