Answer:

<b= 36 degrees, <c= 144 degrees

Step-by-step explanation:

144 and b are supplementary meaning they add up to 180.

144 and c are vertical angles meaning they are congruent.

Ok, 8^(-5) divided by 8^(-3) would be 8^(-5-(-3)), because when you divide numbers with the same base, you subtract the exponents. That would be 8^(-2), which I suppose is A

What is the difference of the lengths of BD and CE ? Use the value (pie) = 3.14, and round the answer to two decimal places.

lys-0071 [83]

Answer:

1.57 units

Step-by-step explanation:

The formula for arc length is given as:

Arc Length = $\frac{\theta}{360}*2\pi r$

Now,

Arc length of BD = $\frac{45}{360}*2(3.14)(6)=4.71$

Arc length of CE = $\frac{45}{360}*2(3.14)(8)=6.28$

The difference in CE and BD is $6.28-4.71=1.57$

Second answer choice is right.

***** CE falls in the larger circle whose radius is AB + BC = 6+2=8

BD falls in the smaller circle whose radius is AB=6

The angles in a triangle are

stira [4]

Answer:

30, 60, and 90

Step-by-step explanation:

Let x be the Angle 1

2x is Angle 2

3x is Angle 3

x + 2x + 3x = 180

6x = 180

x = 30 degrees

2x = 60 degrees

3x = 90 degrees
