Answer:

$=\pm i\sqrt{66}$

Step-by-step explanation:

So we have:

$\pm\sqrt{-66}$

This is the same as:

$=\pm\sqrt{66\cdot-1}$

Separate:

$=\pm\sqrt{66}\cdot\sqrt{-1}$

Replace the second term with i:

$=\pm i\sqrt{66}$

The square root of 66 cannot be simplified.

So, this is our answer :)

Two triangles are said to be congruent if they have similar properties. Thus the required options to complete the paragraph proof are:

a. angle 1 is congruent to angle 2.

b. alternate angles are congruent if two parallel lines are cut by a transversal.

c. $\frac{AD}{CD}$ = $\frac{AB}{CB}$

The similarity property of two or more shapes implies that the shapes are congruent. Thus they have the same properties.

From the given diagram in the question, it can be deduced that

ΔABC ≅ ΔABE (substitution property of equality)

Given that EA is parallel to BD, then:

i. <2 ≅ <3 (corresponding angle property)

ii. <1 ≅ < 4 (alternate angle property)

Thus, the required options to complete the paragraph proof are:

Angle 1 is congruent to angle 2.
Alternate angles are congruent if two parallel lines are cut by a transversal.
$\frac{AD}{CD}$ = $\frac{AB}{CB}$

Wewaii [24]

The complete question is as follows:

Jessica is a custodian at Oracle Arena. She waxes 20 $\mathbf{m^{2}}$ of the floor in $\mathbf{\frac{3}{5}}$ of and hour. At this rate, how many square meters can she wax per hour ?

Answer:

$\mathbf{\frac{100}{3}\approx33.33 \ m^{2} \ per \ hour}$

Step-by-step explanation:

$\textrm{rate}=\frac{\textrm{Area waxed in square meter}}{\textrm{Time taken to wax in hours}}$

$\textrm{rate}=\frac{20 \ \textrm{m}^{2}}{\frac{3}{5} \ \textrm{hours}}$

$\textrm{rate}=\frac{20\times5}{3}$

$\mathbf{rate=\frac{100}{3}\approx33.33 \ m^{2} \ per \ hour}$
