ÐABC = 28°, and ÐBCA is larger than ÐABC. Triangle ABC is an isosceles triangle. It is stated that in an isosceles triangle the two angles are congruent to each other and since one of the angle is given as 28° the measures of two remaining angles is 76°.

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.


***** <u><em>CE falls in the larger circle whose radius is AB + BC = 6+2=8</em></u>

<u><em>BD falls in the smaller circle whose radius is AB=6</em></u>

(12 - 5)2 + (83 - 9x6)
Lesechka [4]

Answer:

78

Step-by-step explanation:

Solve by PEMDAS.

Parentheses first.

12-5 is 7 and 9x6 is 54, 83-54 is 29.

(7)^2+(29)

Exponent next,

49+29

add them up and you get 78.

Hope this helps! Hit the crown if you want.

Find the smallest number by which 35280 must be multiplied so that the product is a perfect square.
nlexa [21]

5 is the <em>smallest</em> number by which 35280 must be multiplied so that the product will be a <em>perfect</em> square.

<h3>What number must be an integer multiplied by to find a perfect square? </h3>

A number is a <em>perfect</em> square if the following property is satisfied:

a = b², where is a <em>natural</em> number.

Please notice that b can be either a <em>prime</em> number or a product of <em>prime</em> numbers.

Initially, we proceed to factorize 35280 by factorial decomposition, that is, as a product of <em>prime</em> numbers:

35280 = 2⁴ × 3² × 5 × 7²

35280 = (2²)² × 3² × 5 × 7²

35280 = 4² × 3² × 5 × 7²

Then, we must add a 5 to find a product that is a perfect square:

4² × 3² × 5² × 7² = 176400

5 is the <em>smallest</em> number by which 35280 must be multiplied so that the product will be a <em>perfect</em> square.
