Answer 1

that's what I did ^^ (in photo)

Answer 2

Answer:

x=56

Step-by-step explanation:

because they are parallel lines, the angle 124 is the same measurement as the angle on the other side of the line with x. (look at the attachment, im bad at explaining with words lol)

then you do 180 - 124 (180 is the angle of a straight line) and you get x.

What is the area of rectangle A?
What is the area of rectangle B?
What is the area of the outer rectangle which measures 3.1 units by 1.4 units?

Answers

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

area =lxb

=3.1units x 1.4units

=4.34units

Answer:

1) 3.1 2) 1.24 C) 4.34

Step-by-step explanation:

Area = l(w)

Area of rectangle A:

3.1 * 1 = 3.1

Area of rectangle B:

0.4 * 3.1 = 1.24

Both rectangles put together:

First, let's add 1 to 0.4... 1.4

1.4 * 3.1 = 4.34

I really, really, really hope I helped you. Good Luck :D

Dennis and Eduardo are studying transformations using triangles. A ABC and A DEF are both plotted on a coordinate plane
Dennis notices that if he reflects A ABC across the y-axis and then translates it down 4 units, the result is A DEF.
Eduardo says that he can first translate A ABC down 4 units and then reflect it across the y-axis in order to get A DEF.
Is Eduardo correct? Explain your answer and tell whether A ABC and A DEF are congruent.
Type your answer in the box below.

Answers

Answer:

i think they are

Step-by-step explanation:

The translation of the 4 units right then a reflection across the x-axis will map triangle ABC onto triangle DEF.

What are the translation and reflections of an image?

Translation of an image indicates the horizontal or vertical movement of that image. The reflection of an image indicates the mirror image of the given image along with a fixed-line.

Here, when we translate the triangle ABC to the right by 3 units, then point A will be at (2, 6), point B will be at (2, 3), and point C will be at (4, 3.).

Hence, after reflecting the triangle ABC, we get the triangle DEF.

both angles have a sum of 180

so if you subtract 62 from 180 then you get 118

Always remember if the angles are attached to a straight line and are only attached to the top or bottom, not both they have a sum of 180.
