ABCD is a square

Mathematics

Look at line CDF and see how it includes all 3 shapes.

The angle of the square is 90 and the equilateral triangle is 60 because 180/3

90 + 60= 150

180 - 150 = 30

Angle ADE is 30 degrees

Since it is an isosceles triangle, the base angels are the same so angle AED is also 30 degrees

You know that DEF is equal to 60 so...

60 + 30 = 90 degrees

Hope this helps and have a nice day!

Pachacha [2.7K]

Answer:

n= 4.7

Step-by-step explanation:

n+−3.66=1.04

n−3.66=1.04

Step 2: Add 3.66 to both sides.

n−3.66+3.66=1.04+3.66

n=4.7

Answer:

n=4.7

2x 5 The area of the rectangle shown is given by the function A()- 2 -5x lfthe width of the rectangle is 13, then the area is 42

PIT_PIT [208]

If you let x = 13:
Then, Area = 2(13)^2 - 5(13)
= 338 - 65
= 273 sq ft

If you let 2x-5 = 13:
2x = 18
x = 6

Then, Area = 2(6)^2 - 5(6)
= 72 - 30
= 42 sq ft

Therefore, your options are A or C. Your answer can be chosen based on what you assume the width to be. Good luck!

Graph, if shifted how much,and which way ?

m_a_m_a [10]

Transformation of Periodic Functions [cos(x)]

For horizontal shifting: +c (left) -c (right)
For vertical shifting: +d (up) -d (down)

For horizontal scaling (period): b↑ compressing b↓ stretching
For vertical scaling (amplitude): a>1 stretching 0<a<1 compressing

Refer to the chart I attached

I hope that helps!

I am with you if you faced any difficulties!
