Using relations in a right triangle, it is found that the length of AC is of 14 cm.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Researching this problem on the internet, we have that:

  • The opposite leg to angle A is of 48 cm.
  • sin(A) = 0.96.

Hence the hypotenuse is found as follows:

sin(A) = 48/h

0.96 = 48/h

h = 48/0.96

h = 50 cm.

The length of side AC is the other leg of the triangle, found using the Pythagorean Theorem, hence:

x^2 + 48^2 = 50^2

x^2 = \sqrt{50^2 - 48^2}

x = 14 cm.

17x - y &lt; 13<br> I’m slope-intercept form
stiks02 [169]

Answer:

y > 17x - 13

Step-by-step explanation:

We want to write the inequality in slope-intercept form

The general slope intercept form is;

y = mx + b

where m is the slope and b is the y-intercept

So what we have to do to the inequality is to make y the subject

Thus, we have that;

17x -13 < y

Flipping this, we have

y > 17x-13

How to solve? Sarah has a $100 she gave 3/4 of the money to her sister. She gave a 1/2 of the rest of the money to her friend. H
kolezko [41]

Answer: $12.50

Step-by-step explanation:

Sarah starts out with $100. She gave 3/4 of it away. 3/4 of 100 is 75. So, that means she gave $75 to her sister. she has $25 left but she gives half of the 25 to her friends. You would divide 25 by 2. since you have to split the 25 in half. she gave away $12.50 and she kept $12.50 for herself. So, she has $12.50 left after giving the money away.

Solve each exponential equation. round your answer to two decimal places.
notka56 [123]

4a.4²x +3=1

Slotuion:

4²x + 3=1 : <em>x</em>= -⅛ (Decimal:<em>x</em>= -0.125)

Steps

4² x +3=1

4²=16

16x + 3=1

Subract 3 from borh sides

16x +3-3=1-3

Simplify

16x=-2

Divides both sides by 16

\frac{16 \times }{16} = [tex] \frac{ - 2}{16}

[/tex]

Simplitfy

\frac{16 \times }{16} :  x

Simplify

\frac{ - 2}{16}: -⅛

<em>x</em> = -⅛

therefore the answer is <em>x</em><em>=</em><em> </em><em>-</em><em>⅛</em>

4b.ex-1 -5 =5

x~=3.30258

explanation:

e^(x-1)=10

x-1=ln 10

x-1~=2.30258

x~=3.30258
