Answer and Step-by-step explanation:
For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = [tex]\frac{x}{15}[/tex]
Multiply both sides by 15.
15(cos(42)) = x
Plug into a calculator.
11.1472 is the answer.

Answer:
16 eighteens fit into [tex]\frac{8}{9}[/tex]
Step-by-step explanation:
in order to find out how much eighteenths are the in [tex]\frac{8}{9}[/tex]. we just have to divide [tex]\frac{8}{9}[/tex] by [tex]\frac{1}{18}[/tex]. So we get...
[tex](\frac{8}{9}) /(\frac{1}{18}) = (\frac{8}{9})(18) = \frac{144}{9} = 16[/tex]

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
Answers
Answer:
500 bricks.
Step-by-step explanation:
There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
To solve e the above question, we have:
20 feet high = 250 bricks
40 feet high = x bricks
Cross Multiply
20 feet × x bricks = 40 feet × 250 bricks
x bricks = 40 feet × 250 bricks/20 feet
x bricks = 500 bricks
Therefore, 500 bricks will be used to build a wall is 40 feet high.

Answers
Answer:
- 65
Step-by-step explanation:

The size of angle x is 25°.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
As per the given data:
The two external angles are given in the diagram.
Assume angles as ∠1, ∠2 and ∠x in anti-clockwise order.
For finding the angles of the triangle:
∠1 + 105° = 180° {linear pair angles}
∠1 = 75°
∠2 + 140° = 180° {linear pair angles}
∠2 = 80°
Using angle-sum property of a triangle:
∠1 + ∠2 + ∠x = 180°
75° + 80° + ∠x = 180°
∠x = 25°
Hence, the size of angle x is 25°.
