9a - 3(a - 6) = -6...distribute thru the parenthesis
9a - 3a + 18 = -6....subtract 18 from both sides
9a - 3a = -6 - 18 ...combine like terms
6a = - 24...divide both sides by 6
a = -24/6
a = - 4

State what additional information is required in order to know what the triangles are congruent by SSS.
soldi70 [24.7K]

Answer:

  see below

Step-by-step explanation:

In order to show congruence by SSS (Side-Side-Side), you need to have 3 pairs of sides congruent. The diagram shows two pairs congruent (those of choice B), so you need information that the third pair of sides is congruent, choice D.

__

Any answer choices involving angles are irrelevant for SSS congruence.

What is the value of x, rounded to the nearest degree? x ≈ ° According to the manufacturer, if the angle the ladder forms with t
DerKrebs [107]

The measure of the value of x is 70.52 degrees.

Given

A 12-foot ladder is placed 4 feet away from a house as shown.

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.

<h3>What is cos angle?</h3>

The cos theta is defined as the ratio of the side adjacent to the angle and the hypotenuse.

The following formula is used to calculate the value of x;

\rm Cosx=\dfrac{Side \ adjacent \ to \ angle}{Hypotenuse}\\

Where the side adjacent to angle = 4 and hypotenuse is 12.

Substitute all the values in the formula;

\rm Cosx=\dfrac{Side \ adjacent \ to \ angle}{Hypotenuse}\\\\\rm Cosx=\dfrac{4}{12}\\\\\rm Cosx=\dfrac{1}{3}\\\\x=Cos{-1}(\dfrac{1}{3}\\\\x= 70.52 \ degrees\\\\

Hence, the measure of the value of x is 70.52 degrees.
