The correct question in the attached figure

we know that
if the triangle ABC was rotated resulting in triangle EFD it implies that it retained it's original dimensions.

This means that ABC is proportional to EFD

hence
AB=EF-------> 4.2 cm
BC=FD-------> 3.6 cm
AC=ED------ > 4.5 cm

the answer is
CB=3.6 cm

Triangle J K L is shown. Angle J K L is a right angle. An altitude is drawn from point K to point M on side J L, forming a right
vredina [299]

Answer:

1, 4, 5

Step-by-step explanation:

Consider right triangle JKL with right angle JKL and height KM. This height divides triangle into two right triangles KML and KMJ.

Note that

m\angle MKL=90^{\circ}-m\angle MLK=m\angle KJM\\ \\m\angle JKM=90^{\circ}-m\angle KJM=m\angle MLK

So, by AA theorem, we have three similar triangles

\triangle JKL\sim \triangle JMK\sim \triangle KML

So, options 1, 4 and 5 are true

According to the chart below, what percentage of Ralph’s expenses are items other than taxes?
pochemuha

Answer:

  • <u>65%</u>

Explanation:

Please, see attached the chart corresponding to this question.

The<em> chart</em> is a pie chart that shows the percentage composition of the <em>expenses </em>and uses color to identify each item.

The items corresponding to<em> taxes</em> are:

  • <em>Federal tax: 29%</em>
  • <em>State tax: 6%</em>

All the other expenses are not taxes.

Add the two items that are taxes: 29% + 6% = 35%.

Hence, the expenses that are not taxes can be calculated by difference:

  • 100% - 35% = 65%.

a marathon is 26.2 miles. If Sally ran a marathon in 3 hours 3 minutes what was her approximate pace in minutes?
Tom [10]

Let's turn 3 hours and 3 minutes into minutes.

One hour=60×3=180+3=183

So, there's 183 minutes in 3 hours and 3 minutes. We need to divide 26.2 miles by 183.

26.2÷183≈ 0.143

So, Sally ran 0.143 miles every minute.

Mariana [72]

Erica earned a total of $50,450 last year from her two jobs. The amount she earned from her job at the store was $1,250 more than four times the amount she earned from her job at the college.

Lets x be the amount she earned from here job at college

amount she earned at the store = 4 * amount earned at college + 1250

= 4x + 1250

Amount earned at college + amount earned at store = 50450

x + 4x + 1250 = 50450

5x + 1250 = 50450

Subtract 1250 from both sides

5x = 49200 (divide by 5)

x = 9840

she earn $9840 from her job at the college
