Answer:

$x=4$

Step-by-step explanation:

$3.9x + 1.4 = 17$

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

$3.9x*10+1.4*10=17*10$

$39x+14=170$

Subtract 14 from both sides:

$39x+14-14=170-14$

$39x=156$

Divide both sides by 39:

$\frac{39x}{39}=\frac{156}{39}$

$x=4$

Answer:

Angle BCD = 25 degrees, angle ABC = 94 degrees, angle ACB = 43 degrees

Step-by-step explanation:

This is an Isosceles triangle, so Angle BCD = 180 - 22 - 133 = 25 degrees.

Angle ABC = 360 - 133 - 133 = 94 degrees.

Angle ACB = (180 - 94)/2 = 43.

How do you Calculate the area of a missing square.

Amiraneli [1.4K]

Answer: Option D

Step-by-step explanation:

Hey there!

Here; Looking at it we can state that it is a Right angled triangle.

And must use the Pythagoras relation if the triangle is a Right angled triangle.

So, let's work on it.

Let ABC be a triangle.

Taking reference angle as C, we get;

perpendicular= 3m

Hypotenuse= 7m

Base = xm

Now;

${h}^{2} = {p}^{2} + {b}^{2}$

$or \: b = \sqrt{ {h}^{2} - {p}^{2} }$

Put all values.

$b = \sqrt{ {7}^{2} - {3}^{2} }$

Simplify to get answer.

$b = \sqrt{49 - 9}$

$b = \sqrt{40}$

Therefore, X= 6.3m.

Hope it helps...

How do you use units and convert them to understand and solve problems

Nina [5.8K]

Units are used as a standard for measurement of the same quantity. It is a definite magnitude of the quantity that is defined by a convection.
Without them we could not be able to measure things.
All physical quantities have their units, For example: length is measured in meters, weight is measured in kilograms, power is measured in watts,...
With units we can understand "physical" problems and have an exact answer of the problem.
