Step-by-step explanation:

angle AEB = 180° - (25°+25°) (isosceles triangle)

= 180° - 50°

= 130°

angle AEB = angle CED = 130° (vertically opp angle)

angle ECD = 25° (alternate angle)

angle CDE = 180° - (25°+130°) (angle sum of a triangle)

= 180° - 155°

= 25°

not sure but here you go^^

2) An $80 text book was on sale for $49.60 at the used book store. By

nadya68 [22]

Answer:

38%

Step-by-step explanation:

Original price = $ 80

Price after reduction = $ 49.60

Reduction = 80 - 49.60 = $30.40

Percentage of decrease = $\frac{reduction price}{original price}*100$

$= \frac{30.40}{80}*100\\\\=\frac{3040}{80}$

= 38%

Simplify the following expression.

love history [14]

Answer:

Step-by-step explanation:

Remember PEMDAS!

So first parentheses:

1.6^2 = 2.56

8.7 + 9.3 = 18.

Because that is inside another parentheses you multipy them.

2.56 x 18 = 46.08

Now: 46.08 divided by 1.8 = 25.6

Now subtract:

25.6 - 3.7 - 1.9 which equals 20!

Hope that helped!

Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.

Lera25 [3.4K]

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C = $2\pi r$

Plug 35 in for r (radius) and solve.

C = $(35) 2\pi\\\\C = 70\pi\\\\C = 219.9$

So, approximately 219.9 $in^2$ is the answer.
