Answer:

(B) Luis's, because he flipped the inequality sign when he subtracted

Step-by-step explanation:

Let's evaluate each answer choice:

<u>"Amelia's, because the variable term must be isolated on the left side"</u>

This answer choice is wrong! Whichever side the variable term is isolated on DOESN'T affect the answer of the problem.

<u>"Luis's, because he flipped the inequality sign when he subtracted"</u>

This answer choice is right! Only flip the inequality sign when dividing a NEGATIVE number.

<u>"Shauna's, because she did not apply the subtraction property of equality properly"</u>

This answer choice is wrong! Shauna correctly applied the subtraction proper by subtracting 6.5 from both sides.

<u>"Clarence's, because the terms he added together were not like terms"</u>

This answer choice is wrong! Clarence added 8.1 to both sides, so he added 8.1 to 6.5, which are like terms.

Hope it helps (●'◡'●)

In triangle △ABC, ∠ABC=90°, BH = altitude
Ainat [17]

Answer: The exact length of segment HC is sqrt(3) units

The approximate length is roughly 1.73205080756888 (round that however you need to)

==============================================

Work Shown:

Let x = length of HC

Since AH = 3*HC, this means AH = 3*x

Draw out the picture. This step is optional but helpful in my opinion. The drawing is attached below.

After adding in the altitude BH, we have three similar triangles. So we can form the proportion shown below to solve for x

HC/BH = BH/AH

HC/3 = 3/AH ... replace BH with 3

x/3 = 3/AH ... replace HC with x

x/3 = 3/(3x) ... replace AH with 3x

x/3 = 1/x ... reduce

x*x = 3*1 ... cross multiply

x^2 = 3

x = sqrt(3) ... which is shorthand for "square root"

HC = sqrt(3)

HC = 1.73205080756888 which is approximate

I know how to do it but don’t have a calculator with the trig option sin-1 so can someone help me
Nina [5.8K]

Answer:

x = 4.9 cm

Step-by-step explanation:

Note that sin theta = (opp side) / (hypotenuse), and that:

hypotenuse      (opp side)

------------------ = -----------------

         1                sin theta

and so:

hypotenuse      (opp side)                                           4 cm

------------------ = -----------------  or  hypotenuse = ---------------------------- = x

         1                sin theta                                     sin (55 degrees)

   

                     4 cm

Thus, x =  --------------- = x = 4.88 cm or (to 1 DP)        x = 4.9 cm

                    0.819
