\dfrac{3b^2}{4a^2}+\dfrac{5b}{3a}-\dfrac{1}{6a^3}=\dfrac{3b^2\cdot3a}{4a^2\cdot3a}+\dfrac{5b\cdot4a^2}{3a\cdot4a^2}-\dfrac{1\cdot2}{6a^3\cdot2}\\\\=\dfrac{9ab^2}{12a^3}+\dfrac{20a^2b}{12a^3}-\dfrac{2}{12a^3}=\boxed{\dfrac{20a^2b-2+9ab^2}{12a^3}}

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.)

Alexus [3.1K]
Let the cost of renting a chair be x and for renting a table be y than 5x + 3y = 31 and 2x + 6y = 52 2x+ 6y = 52 can be further simplified to x + 3y = 26 now try solving for x and y... best of luck:D
