What is the value of x?

tensa zangetsu [6.8K]

Answer:

X = 5°

Step-by-step explanation:

180° on a straight line.

180 - 100 = 80 angle ABC = 80°

angle ACB is vertically opposite to the 60° given

ACB = 60°

180 - 80 - 60 = 7x+5

40 = 7x + 5

7x = 35

X = 5

Tan9°. tan27°. tan45°. tan72°. tan81°= 1 could u plz solve it with clear process

Inga [223]

Correct question:-

Prove that tan9.tan17.tan45.tan73.tan81=1

LHS

$\\ \sf\longmapsto tan9.tan17.tan45.tan73.tan81$

$\\ \sf\longmapsto tan9.tan81.tan17.tan73.tan45$

$\\ \sf\longmapsto tan(90-81).tan81.tan(90-73).tan73.1$

$\\ \sf\longmapsto cot81.tan81.cot73.tan73$

$\\ \sf\longmapsto 1.1$

$\\ \sf\longmapsto 1$

In the arithmetic sequence {13,6,−1,−8,…}, what is the common difference? Enter your answer as a number, like this: 42

V125BC [204]

Answer:

-7

Step-by-step explanation:

To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:

6 - 13 = -7

To check you can do the same thing with other consecutive numbers in the sequence like:

-1 - 6 = -7

Find a bijection from (0,1] to (0,1) Math: Analysis and proof

gregori [183]

Answer with explanation:

The meaning of bijection for two sets X and Y is each and every element of X is uniquely related with element of set Y and when you take the inverse mapping every element of set Y is uniquely related with each and every element of Set X.

The two sets given are

X=(0,1]---------Semi open or Semi closed Set

Y=(0,1)---------Closed set

Between any two real numbers there are infinite number of real numbers.So cardinal number of both the sets is infinite.

There can be infinite bijection between these two sets as both sets have infinite number of elements.

X Y

0.1 ------------- 0.01

0.2 ------- 0.02

0.3 -------- 0.03

0.4 --------- 0.04
