An example of congruence similarity and transformations work is " If the measures of the angles of a triangle are in the ratio 4 : 5 : 9. The triangle is?.
<h3>What is right angled triangle?</h3>
A right triangle is known to be often called right-angled triangle. It is said to be a triangle that is composed of one angle which is at a right angle and two sides which are said to be perpendicular.
So lets take the angles to be 4x, 5x and 9x
We add them to be 4x + 5x + 9x =180°
18x=180° =
x= 180/18
x = 18
So therefore the angles are:
4×10°
=40°
5×10°
=50°
9×10°
=90°
So therefore since one of the angle is 90° and as such, the triangle is right angled triangle.

Answer:
71% of the earth forms water
Explanation:
About 71% of the earth is covered with water out of which approximately 97% is ocean and the remaining includes rivers, lakes and streams. Glaciers made up to 2% and a tiny fraction is in the form of vapors. Water covers vast majority of the earth planet. The other 29% of earth consists of islands and continents.
For this we will use kinematic equations.
We need the time of flight to compute the range.
With the given information, the most useful formula is:
Δy=v0yt−g2t2
Because our equation is taking only vertical motion into account,
v0y=30sin(45)
Because we are looking for the range of the object,
Δy=0
This leaves us with only one unknown: t
0=30sin(45)t−g2t2
g2t2=30sin(45)t
g2t=30sin(45)
t=60gsin(45)
For horizontal distance, the formula we need is:
Δx=v0xt
Because we are taking into account the horizontal range,
v0x=30cos(45)
In substituting our derived values into the equation we can see that:
Δx=30cos(45)∗60gsin(45)
Range=30cos(45)∗60gsin(45)
All positive solutions, including zero:
2x - 1 < 3
2x < 4
x < 2
solutions (integers): 0 and 1
All negative solutions:
2x - 1 < -3
2x < -2
x < -1
Since the question is asking you for solutions that are non-negative integers, the answer is 0 and 1.
Answer:
The solution is more acidic and is closer to become neutral.
Explanation:
Acidic level: 0 - 6
Neutral: 7
Alkaline level: 8 - 14
From this, we can see that the given solution went from a higher alkaline concentration level to a lower one.
