Answers

Answer 1

Answer:

The measure of angle BCA = The measure of angle C prime A prime B prime

Step-by-step explanation:

Answer 2

The correct relationship between the measures of the angles of the two triangles is;

The measure of angle BCA = The measure of angle C prime A prime B.

Given that

Triangle ABC is transformed to triangle A′B′C′, as shown below:

A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes.

A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.

A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.

We have to determine

Which equation shows the correct relationship between the measures of the angles of the two triangles?

According to the question

Triangle ABC is transformed to triangle A′B′C′, as shown below:

Here the triangle ABC is similar A'B'C' are similar triangles.

For similar triangles angles are congruent.

A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.

A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.

Therefore,

<BAC = <B'A'C'

<ABC = <A'B'C'

<ACB = <A'C'B'

Hence, The correct relationship between the measures of the angles of the two triangles is The measure of angle BCA = The measure of angle C prime A prime B.

Kara works at a fine jewelry store and earns commission on her total sales for the week. Her weekly paycheck was in the amount of $7000, including her salary of $1000. Her sales for the week totaled $50,000. Express her rate of commission as a percent, rounded to the nearest whole number.

Answers

Her total paycheck minus her salary = the commission amount
So
6500 - 1000 = 5500
So....her commission as a percentage of sales = 5500/ 45000 = about 12.2%

D.

Answers

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps

!!!(URGENT)!!! What is the surface area of this figure

Answers

Answer:

36 inches

Step-by-step explanation:

if you unfold the triangular prism and find the area of each individual shape, all you have to do is add them up:

Area Of Rectangle = WL

Area Of Triangle = 1/2(HB)

5x2=10

4x2=8

3x2=6

(4x3)1/2=6x2=12

10+8=18+6=24+12=36
