Let a, b, c and x elements in the group G. In each of the following solve for x in terms of a, b, and c.

Nezavi [6.7K]

Answer:

$x=c.a^{-1}.b^{-1}$

Step-by-step explanation:

Given equation,

$axb = c-----(1)$

$(axb) ( a^{-1}.b^{-1} ) = c.(a^{-1}b{-1})$

$(xb)(a)(a^{-1}.b^{-1} ) = c.(a^{-1}b{-1})$ ( commutative law of multiplication )

$(xb)(a.a^{-1}).b^{-1} = c.a^{-1}b{-1}$ ( Associative property )

$(xb).e.b^{-1} = c.a^{-1}b{-1}$

$(xb).b^{-1}=c.a^{-1}.b^{-1}$ ( identity property )

$x.(b.b^{-1})=c.a^{-1}.b^{-1}$ ( Associative property )

$x.e=c.a^{-1}.b^{-1}$

$x=c.a^{-1}.b^{-1}$ ( identity property )

in the triangles shown, abc is dilated by factor of 2/3 to form xyz. given that angle a is 50 degrees and angle b is 100, what i

Anvisha [2.4K]

We know that

in the triangle ABC
∡A+∡B+∡C=180°
∡C=180-(50+100)-------> ∡C=30°

triangle ABC and triangle XYZ are similar
so
∡X=∡A
∡Y=∡B
∡Z=∡C
hence
∡Z=30°

the answer is
∡Z=30°

What is the APPROXIMATE circumference of a circle with a radius of 9 inches? Use 3.14 for π. 28.3 in. 56.5 in. 254.34 in. 113.0

Stella [2.4K]

Answer:

56.52 in

Step-by-step explanation:

Circumference Formula: C = 2πr

Since we are given radius <em>r</em> = 9, simply plug it into the formula:

C = 2π(9)

C = 18π

C = 56.5487

What is the measure of <A

Alecsey [184]

Answer:

98 degrees.

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral add up to 180 degrees.

So m <A + 82 = 180

m<A = 180 - 82 = 98 degrees.
