angle b = 90 degrees, side bc = 20, angle y = 90 degrees, and side yz = 20. what additional information would you need to prove that δabc ≅ δxyz by hl? angle a is congruent to angle x. angle b is congruent to angle y.
(c is wrong)

The additional information would you need to prove that ΔABC ≅ ΔXYZ by HL is

Side AC is congruent to side XZ

Step-by-step explanation:

Given:

Angle B = 90 degrees,

side BC = 20,

angle Y = 90 degrees, and

side YZ = 20

To Prove:

ΔABC ≅ ΔXYZ by HL

Proof:

In  Δ ABC and Δ XYZ

BC ≅ YZ     ……….{measure of each sides 20 given}

∠B ≅ ∠Y     …………..{measure of each angle is 90° given}

AC ≅ XZ     ……….{additional information}

Δ ABC ≅ Δ PQR ….{By Hypotenuse Leg Theorem}

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
