The additional information is required in order to know that the triangle are congruent is, GW ≅ WX.
What is congruent triangles?
If each of the three corresponding sides and each of the three corresponding angles in two triangles equals one another, then the two triangles are said to be congruent.
We have to show that the the triangles ΔVWX and ΔEWG are congruent by using the AAS (angle, angle, side) criteria.
From the given reasons,
∠V ≅ ∠E
∠VWX ≅ ∠EWG
From this the AA criteria is satisfied.
We want sides of the triangle are congruent.
From the figure, GW ≅ WX
Therefore, by AAS the two triangles ΔVWX and ΔEWG are congruent.

length of the base.
The length of the base is 22.1
An isosceles triangle with congruent sides of length 49.3 inches has a perimeter of 121.7 inches
An triangle is said to be isosceles if two sides of the trainagle have same length.
The two sides of this triangle is congurent that is they have same length = 49.3
perimeter of a triangle is the summation of all three sides.
Perimeter = length + base + length
121.7 = 49.3 + base + 49.3
base = 121.7 - 99.6
base = 22.1
Therefore, the length of the base is 22.1

explain what a,h, and k do to transform the parent absolute function y=|x| to the function y= a|x|…
The a ,h and k values affect the parent absolute function ,by altering the the size , causing horizontal and vertical movements respectively.
How do the a , h and k values affect the function?a )a values
a values affect the size of the graphed parent absolute function and they have a scalar factor.When a is greater than 1 , we have a vertical stretch (Taller appearance )and a horizontal compression (Thinner appearance).When a is between 0 and 1 , we have a vertical compression( Shorter appearance) and a horizontal stretch ( wider appearance).b ) h values
h values cause left or right movement of the graph, which is known as the horizontal shift or translation.When h is negative, the graph moves right.When h is positive , the graph moves left.c ) k values
k values cause up and down movement ,which is known as the vertical shift or translation.When k is negative, the graph moves down.When k is positive , the graph moves up.To learn more about parent absolute function, refer:

What is Linear approximation ?
A linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations.
The formula is
L(x) = f(a) + f'(a) (x - a)
Given,
y = sin(2x)
Δx = 0.1 at x = 0
y'(x) = dy/dx = 2 cos 2x
As, x = 0
y'(0) = 2 cos 0
we know, cos 0 = 1
y'(0) = 2
Δy = y'(x) * Δx
= y'(0) * Δx
= 2 * 0.1
Δy = 0.2 (Approx value)
Exact value of Δy = sin(2 * 0.1) - sin 0
= sin(0.2) - 0
= 0.19867
% error = [ (Exact value - Approx value) / Exact value ] * 100
= [ (0.2 - 0.19867) / 0.19867 ] * 100
= 0.66945 or 0.67%
Hence, the percentage error is 0.67%

Write the given expression as an algebraic expression in x. tan(2 sin^-1(x))
The trigonometric ratio tan(2 sin⁻¹(x)) is expressed as 2sec(x)
Trigonometric RatioThe six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
In the question given, we have;
tan(2 sin⁻¹(x))
tan = sin / cos
sin/cos(2 * 1/sin x)
The expression becomes 2/cosx or 2cos⁻¹(x)
But cos⁻¹ = sec
tan(2 sin⁻¹(x)) = 2sec(x)

in a class of 50 student 35 are girls what is the probability that a student selected at random is a boy
find the value of b/a if a+1/b-1=5/1 and a-1/b+1=1/1
Answer:
1/2
Step-by-step explanation:
You want the value of b/a when (a+1)/(b-1)=5/1 and (a-1)/(b+1)=1/1.
SolutionThe latter equation tells you ...
a -1 = b +1
b = a -2
Then the first equation tells you ...
a +1 = 5(b -1)
a +1 = 5(a -2 -1) substitute for b
a +1 = 5a -15 . . . . eliminate parentheses
16 = 4a . . . . . . . . add 15 -a
4 = a . . . . . . . . . divide by 4
b = a -2 = 4 -2 = 2 . . . . find the value of b
b/a = 2/4 . . . . . . . . . . find the desired ratio
b/a = 1/2
