Answer:

x = 20, angle B = 92, angle C = 40

Step-by-step explanation:

Solve for x.

48 + 6x - 28 + 2x = 180

8x + 20 = 180

8x = 160

x = 20

Angle B = 6(20) - 28 = 92

Angle C = 2(20) = 40

Proof: 48 + 92 + 40 = 180

Answer:

x=20

m<B=92 degrees

m<C=40 degrees

Step-by-step explanation:

48+6x-28+2x=180

20+8x=180

8x=160

x=20

(6(20)-28)=92

2(20)=40

So, x=20, m<B=92 degrees and m<C=40 degrees

The areas of two similar triangles are 20m2 and 180m2. The length of one of the sides of the second triangle is 12m. What is the

guajiro [1.7K]

Answer:

The corresponding side of the first triangle is 4 m.

Step-by-step explanation:

Area of the first triangle: A1=20 m^2

Area of the second triangle: A2=180 m^2

Lenght of one of the sides of the second triangle: s2=12 m

Corresponding side of the first triangle: s1=?

A1/A2=(s1/s2)^2

Replacing the known values:

(20 m^2)/(180 m^2)=[s1/(12 m)]^2

Simplifying:

2/18=[s1/(12 m)]^2

Simplifying the fraction on the left side of the equation dividing the numerator and denominator by 2:

(2/2)/(18/2)=[s1/(12 m)]^2

1/9=[s1/(12 m)]^2

Solving for s1: Square root both sides of the equation:

sqrt(1/9)=sqrt{[s1/(12 m)]^2}

sqrt(1)/sqrt(9)=s1/(12 m)

1/3=s1/(12 m)

Multiplying both sides of the equation by 12 m:

(12 m)*(1/3)=(12 m)*s1/(12 m)

Simplifying:

(12 m)/3=s1

4 m=s1

s1=4 m

Which expression is equivalent to (4^5/4 4^1/4/4^1/2) ^1/2

Lilit [14]

The expression is equivalent to 2 , Option C is the correct answer.

<h3>What is an Expression ?</h3>

An expression is a mathematical statement consisting of variables , constants and mathematical operators.

The expression given in the question is

$\rm( {\dfrac{4^{5/4} * 4^{1/4}}{4^{1/2}}})^{1/2}$

By exponent rule

$\rm a^m * a^n = a^{m+n}\\\\a^m \div a^n = a^{m-n}$

Here so ,

$\rm 4^{(\dfrac{5}{4} +\dfrac{1}{4} -\dfrac{1}{2})^{1/2}$

$\rm 4^{(\dfrac{6}{4} -\dfrac{1}{2})^{1/2}\\\\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\$

$4^{(\dfrac{6-2}{4} )^{1/2}\\$

$4^{1/2}\\\\(2^2)^{1/2}\\\\2$

Therefore the expression is equivalent to 2 , Option C is the correct answer.
