The lengths of the two sides of a triangle (not necessarily a right triangle) are 1.00 meters and 3.54 meters. The sine of the a
DerKrebs [107]

Answer:

sin B= 0.096288

B = 5.525°

Step-by-step explanation:

Consider ΔABC as shown in figure attached

From figure:

a = 1 m

b = 3.54 m

sin A = 0.0272

sin B = ?

Using the sine rule for non-right-angle triangle

\\\frac{a}{sin\, A}=\frac{b}{sin\,B}\\\\sin\,B=\frac{b(sin\,A)}{a}\\\\sin\,B=\frac{(3.54)(0.0272)}{1}\\\\sin\,B=0.096288\\\\B= 5.525^o

A pair of shoes is on sale for 30% off. The original price is p. Which expression can be used to find the price of the shoes aft
Sidana [21]

The correct option is b which is 0.70p.

Given to us,

original price of shoes = p,

Discount on shoes = 30%

As we know after giving the discount the value of the shoes will be 70% of the original price, therefore,

\bold{p=100\%\ price\ of\ shoes = \dfrac{100}{100}\times p = p}

After 30% discount,

\bold{p=(100\%-70\%) price\ of\ shoes}

\bold{p=70\%\ price\ of\ shoes = \dfrac{70}{100}\timesp= 0.7p }

Hence, the correct option is b which is 0.70p.

The question is below, plz answer, will give brainliest
Elina [12.6K]

By comparing the right triangle ABC with the triangle XYZ, we will see that:

  • AC = 5
  • BC = 10.

<h3>How to find the given segments?</h3>

So we know that the largest triangle is a dilation of scale factor 2 of the smaller one.

Also, remember that for right triangle we have the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Now, the problem tells us that:

tan(x) = 5/2.5

For the angle x, the adjacent cathetus is XY, and the opposite cathetus is YZ.

Then we have:

YZ  = 5

XY = 2.5

Knowing that the correspondent sides in the larger triangle will be 2 times the above ones, we can see that:

AC = 2*XY = 2*2.5 = 5

CB = 2*YZ = 2*5 = 10
