120+4p=400

4p=280

p=70

So he read 70 pages a day after the first day.

If BC= 48 cm and sin
erastovalidia [21]

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.

Find the greatest common factor (GFC) for this pair of composite numbers. 10 and 15
zloy xaker [14]

Given:

The pair of composite numbers: 10 and 15

To find:

The greatest common factor (GFC) for the given pair of composite numbers.

Solution:

Two composite number are 10 and 15.

The factor forms of these two numbers are

10=2\times 5

15=3\times 5

It is clear that the common factor is 5 in both factor forms. So, the greatest common factor is

GCF(10,15)=5

Therefore, the greatest common factor of 10 and 15 is 5.

Use a special right triangle to find the value of y. Write as a decimal rounded to the nearest 10th
VladimirAG [237]

Given:

The figure of a right angle triangle.

To find:

The value of y.

Solution:

in a right angle triangle,

\sin \theta=\dfrac{Opposite}{Hypotenuse}

In the given right triangle,

\sin 60^\circ=\dfrac{6}{y}

\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}

On cross multiplication, we get

\sqrt{3}y=12

y=\dfrac{12}{\sqrt{3}}

y=\dfrac{12\sqrt{3}}{3}

y=4\sqrt{3}

Therefore, the value of y is 4\sqrt{3} units.
