The value of ∠EOF is 75°.

Step-by-step explanation:

Let us take O be the center of the circle.

Given,

∠AOB = 45°

∠COD = 60°

To find the ∠EOF (value of x)

Now,

Since AD is the diameter of the circle, ∠AOD = 180°

∠AOB+∠COD+∠BOC = ∠AOD

Or, 45°+60°+∠BOC = 180°

or, ∠BOC = 180°-(45°+60°)

= 75°

Again,

∠BOC = ∠EOF as they are vertically opposite angle.

Hence,

∠EOF = 75°

How to solve this? Is the question correct? ty :)

Answer:

The proposition is true.

Step-by-step explanation:

Now we proceed to demostrate that expression given is true by algebraic means:

1) $\frac{x^{-1}+y^{-1}}{x^{-1}}+\frac{x^{-1}-y^{-1} }{y^{-1}}$ Given

2) $\frac{y^{-1}\cdot (x^{-1}+y^{-1})+x^{-1}\cdot (x^{-1}-y^{-1})}{x^{-1}\cdot y^{-1}}$ $\frac{a}{b} + \frac{c}{d} = \frac{a\cdot d+b\cdot c}{b\cdot d}$

3) $\frac{x^{-1}\cdot y^{-1}+y^{-2}+x^{-2}-x^{-1}\cdot y^{-1}}{x^{-1}\cdot y^{-1}}$ Distributive property/ $a^{b}\cdot a^{c} = a^{b+c}$

4) $\frac{x^{-2}+y^{-2}}{(x\cdot y)^{-1}}$ Commutative, associative and modulative properties/Existence of additive inverse/ $a^{b}\cdot c^{b} = (a\cdot c)^{b}$

5) $[(x\cdot y)^{-1}]^{-1}\cdot (x^{-2}+y^{-2})$ Commutative property/Definition of division

6) $(x\cdot y)\cdot (x^{-2}+y^{-2})$ $(x^{-1})^{-1}$

7) $x^{-1}\cdot y + x\cdot y^{-1}$ Distributive property/Associative property/ $a^{b}\cdot a^{c} = a^{b+c}$

8) $(x^{-1}\cdot y^{-1})\cdot y^{2} + (x^{-1}\cdot y^{-1})\cdot x^{2}$ Modulative property/Existence of additive inverse/ $a^{b}\cdot a^{c} = a^{b+c}$

9) $(x^{-1}\cdot y^{-1})\cdot (x^{2}+y^{2})$ Distributive property

10) $(x\cdot y)^{-1}\cdot (x^{2}+y^{2})$ $a^{b}\cdot c^{b} = (a\cdot c)^{b}$

11) $\frac{x^{2}+y^{2}}{x\cdot y}$ Commutative property/Definition of division/Result

If you know two points on a line, how can you find the rate of change of the variables being graphed?

Leto [7]

Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
