Answer:

  c = √73

Step-by-step explanation:

The Pythagorean theorem tells you that ...

  c² = a² + b²

The sides you choose to call 'a' and 'b' don't matter. We can let 'a' be the left side and 'b' be the top side. Then we have ...

  c² = 3² +8² = 9 + 64 = 73

Taking the square root gives ...

  c = √73

Answer:

c = [tex]\sqrt{73}[/tex]

Step-by-step explanation:

c is the hypotenuse ( side opposite to the right angle )

So,

[tex]c^{2}[/tex] = [tex]8^{2}[/tex] + [tex]3^{2}[/tex]        (Pythagoras theorem)

c = [tex]\sqrt{64 + 9}[/tex]

c = [tex]\sqrt{73}[/tex]

Make s the subject of the formula

Answers

Answer:

choose option E.

Step-by-step explanation:

Given

.Making s as the subject

as = t² - 2p

s = ( t² - 2p) / a

t² = 2p + as

t² - 2p = as

(t² - 2p)/a = s

Cross multiply,

Use distributive property: a*(b + c) =(a*b) + (a*c)

qt + 3q = 2- 4t

A ladder is leaned against a wall that is six feet tall, so that the top of the ladder is resting on the top
of the wall. The ladder is inclined at an angle of thirty degrees. Find the distance from the bottom of
the ladder to the base of the wall. Round your answer to the nearest tenth of a foot. Do not include
units in your answer.

Answers

Answer:

[tex]10.4[/tex]

Step-by-step explanation:

The ladder leaning against the wall forms a right triangle with the wall and the ground. Therefore, we can use basic trig for a right triangle to solve this problem.

In a right triangle, [tex]\tan\theta=\frac{\text{opp}}{\text{adj}}[/tex]. Therefore, we have the following equation, where [tex]x[/tex] is distance between the bottom of the ladder to the base of the wall:

[tex]\tan 30^{\circ}=\frac{6}{x},\\x=\frac{6}{\tan 30^{\circ}},\\x\approx \boxed{10.4}[/tex].

Find the measure of angle a.

Answers

Answer:

a = 127°

Step-by-step explanation:

The 3 angles lie on a straight line and have a sum of 180°, that is

53° + a = 180° ( subtract 53° from both sides )

a = 127°

Find the side length of a square with
area 16/49 square inches.

Answers

Each side of a square is the same, so the area of a square is one side times another of the same length. In other words it's side x side or side2

This is where we get the term "square root".

s2 = 49
take the square root of each side
s = 7

The side length of this square is equal to [tex]\frac{4}{7}\;inches[/tex]

Given the following data:

Area of a square = [tex]\frac{16}{49}[/tex] square inches.

To determine the side length of this square:

In this exercise, you're required to solve for the length of the sides of a square that has an area of  [tex]\frac{16}{49}[/tex] square inches.

Formula for the area of a square.

Mathematically, the area of a square is calculated by using the formula;

[tex]A=S^2[/tex]

Where;

S is the length of each sides of a square.

Substituting the value into the formula, we have;

[tex]\frac{16}{49}=S^2[/tex]

Taking the square root of both sides, we have;

[tex]S=\sqrt{\frac{16}{49}} \\\\S=\frac{4}{7}\;inches[/tex]
