What is the answer of this question plzzzzzzzzzzz say fast

Softa [21]

Answer:

$1=3=70^{0} \\2=4=5=110^{0}$

Step-by-step explanation:

Given angle is 110°

Now,

$4=2\,\,and\,\,4=5\,\,;[vertical\,\,angle\,\,and\,\,corresponding\,\,angle\,\,respectively ]$

From the figure,

$4=110^{0}\,\,;[alternate\,\,angle]$

$So,\,\,2=5=110^{0}$

And, as 1,2,3,4 are vertical angles and 2 = 4 = 110°

1 = 3 = 180° - 110° = 70°

Hope you have understood this.....

ask me if you have any confusion.....

2, 6, 10, 15, ... O Arithmetic O Geometric O Neither

natima [27]

Given:

The sequence is:

2, 6, 10, 15,...

To find:

Whether the given sequence is Arithmetic, Geometric, Neither.

Solution:

We have,

2, 6, 10, 15,...

Different between consecutive terms are:

$6-2=4$

$10-6=4$

$15-10=5$

Since $4\neq 5$ , therefore the given sequence has no common difference. It means it is not an arithmetic sequence.

Ratio of consecutive terms are:

$\dfrac{6}{2}=3$

$\dfrac{10}{6}=\dfrac{5}{3}$

Since $3\neq \dfrac{5}{3}$ , therefore the given sequence has no common ratio. It means it is not a geometric sequence.

Since the given sequence is neither arithmetic nor geometric, therefore the correct option is C.

Who wants to be the brainliest? Rearrange the formula C = 2πr for r.

faltersainse [42]

Answer:

B) r= c/2 $\pi$

Step-by-step explanation:

To isolate r, divide 2 $\pi$ on both sides

c = 2 $\pi$ r

-- --

2 $\pi$ 2 $\pi$

c/2 $\pi$ =r

Hope this helps! :)
