Basic theorems on similarity of trianglesTheorem 1 :- SSS Similarity
When all the three sides of one triangle are in proportion to the other three sides of the another triangle then those 2 triangles are similar by SSS similarity .Theorem 2 :- AA similarity
When the two corresponding angles of one triangle are congruent to other two corresponding angles of another triangle then both the triangles are similar by AA Similarity .Theorem 3 :- SAS similarity
When the two sides of one triangle are in proportion to the other two sides of another triangle and the one of the angles of both the triangles that lie between two corresponding sides are equal then both the triangles are similar by SAS similarity.Theorem 4 :- AAA similarity
When all the three angles of one triangle are equal to other three angles of another triangle then both the triangles are similar by AAA similarity. Let's Begin :-Here, We have given statement that
" If an angle of one triangle is congruent to an angle of another triangle and the corresponding sides including those angles are in proportion, then the two triangles are similar . "From above theorem, we can conclude that
Both the triangles are similar by SAS similarityHence, Option C is correct
[tex]\bold{\huge{\underline{ Solution \: 2 }}}[/tex]
The given statement is proved by using Pythagorean theorem.
Pythagorean theorem states that the square of hypotenuse that is longest side is equal to the sum of the squares of base and perpendicular height that is the smallest sides of the given triangle.That is,
[tex]\sf{\red{ (Hypotenuse)^{2} = ( Perpendicular)^{2} + ( Base) ^{2}}}[/tex]
Hence, Option D is correct that is Pythagorean theorem.

A 390 m wire is cut into three pieces. The second piece Is 4 times as long as the first. The third plece is 2 times as long as the second. How long is each piece?
Answers
Answer:
First piece = 30m , 2nd is 120 m and third piece is 240 m long.
Step-by-step explanation:
Let the length of the first piece be x m.
Then the length of the second piece = 4x m.
The third piece = 2 * 4x = 8x m.
So x + 4x + 8x = 390
13x = 390
x = 30 m
So 2nd piece = 4*30 and third is 8*30 m.

How tall would a building have to be if, after hitting the ground ten times, the ball bounces to 1 m? Is there a building this tall?
Answers
The building should be 1.024 meters high and unfortunately there are no buildings with such height in the world.
How to estimate the height of a building by geometric progressionsIn this question we must use definition of geometric progression to predict initial height ([tex]h_{o}[/tex]), in meters, in terms of current height ([tex]h[/tex]), in meters, and number of bounces experimented by the ball ([tex]n[/tex]). The expression is described below:
[tex]h = h_{o}\cdot \left(\frac{1}{2} \right)^{n}[/tex] (1)
If we know that [tex]n = 10[/tex] and [tex]h = 1\,m[/tex], then the initial height is:
[tex]1 = h_{o}\cdot \left(\frac{1}{2} \right)^{10}[/tex]
[tex]h_{o} = 2^{10}[/tex]
[tex]h_{o} = 1024\,m[/tex]

Evaluate ∫ sin(x) cos(x) dx by four methods.
a. The substitution u = cos(x)
b. The substitution u = sin(x)
c. The identity sin(2x) = 2 sin(x) cos(x)
d. Integration by parts.
Answers
(a) Since u = cos(x) gives du = -sin(x) dx, we have
∫ sin(x) cos(x) dx = - ∫ (-sin(x)) cos(x) dx
= - ∫ cos(x) d(cos(x))
= - ∫ u du
= - 1/2 u² + C
= -1/2 cos²(x) + C
(b) Now u = sin(x) gives du = cos(x) dx, so
∫ sin(x) cos(x) dx = ∫ sin(x) d(sin(x))
= ∫ u du
= 1/2 u² + C
= 1/2 sin²(x) + C
(c) Since sin(2x) = 2 sin(x) cos(x), we have
∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx
Substitute u = 2x, so that du = 2 dx, and
∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx
= 1/4 ∫ 2 sin(2x) dx
= 1/4 ∫ sin(u) du
= -1/4 cos(u) + C
= -1/4 cos(2x) + C
(d) Integrate by parts, setting
u = sin(x) ==> du = cos(x) dx
dv = cos(x) dx ==> v = sin(x)
Then
∫ sin(x) cos(x) dx = sin²(x) - ∫ sin(x) cos(x) dx
2 ∫ sin(x) cos(x) dx = sin²(x) + C
∫ sin(x) cos(x) dx = 1/2 sin²(x) + C
The solutions in (b) and (d) are identical, but all 4 are equivalent, and this follows from the identities,
sin²(x) + cos²(x) = 1
cos(2x) = cos²(x) - sin²(x)
