from the top of the tower the angle of depression of a bottom of a pillar on the same surface of height is 20 metre is 60 degree. if the angle of depression from the top of the pillar to the bottom of a tower is 22 degree. find the height of the tower.​

Answers

Answer 1

Answer:

85.74 m.

Step-by-step explanation:

tan 22 = 20/x where x is the distance between the tower and the pillar.

x = 20 tan 22 = 49.50.

tan 60 = h/49.50   where h is height of the tower

h = 49.5 tan 60

= 85.74 m.

x<5

Answers

Answer:

There will be no real solution. A further explanation is given below.

Step-by-step explanation:

The given equation is:

⇒ [tex]7x-12<7(x-1)[/tex]

On solving bracket, we get

⇒ [tex]7x-12<7x-7[/tex]

On putting numbers on the right side and x's on the left side of the equation, we get

⇒ [tex]7x-7x<-7+12[/tex]

⇒ [tex]0<5[/tex]

Thus the above is the appropriate solution.

When solving a system of equations, Jared found y = x + 10 for one equation and substituted x + 10 for y in the other equation. Nicole found x = y – 10 for the same equation and substituted y – 10 for x in the other equation. Who is correct? Explain.

Answers

Answer:

Jared and Nicole are correct.

Step-by-step explanation:

You can solve for either variable and use the equivalent expression to create a one-variable equation. They manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. For both solutions, they'll still get the same answers.

Step-by-step explanation:

complementary angles add up to 90o

x+(x-34) =90

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.

Answers

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (3/4)

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

_______________________________________________

The answer is 35.1 cm².

write an expression equivalent to `b+b+b+b+b` that is a product of a coefficient and a variable.

Answers

Answer:

b^5

Step-by-step explanation:

The expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have:

= b+b+b+b+b

Here, b is the variable after adding b five times we get:

= 5b

5 is the coefficient and b is a variable.

Thus, the expression `b+b+b+b+b` is equivalent to 5b, which is a product of a coefficient and a variable.
