C. HA (Hypotenuse angle congruence).

Step-by-step explanation:

We have been given a diagram of two right triangles. We are asked to choose the correct congruence theorem for our given triangles.

In our triangles ABC and DEF we have,

$m\angle C=m\angle F=90^o$

AB=DE

$\angle A=\angle D$

We can see that side length AB is hypotenuse of triangle ABC and side length DE is hypotenuse of triangle DEF.

Angle A and angle D are acute angles (less than 90 degrees) as we have one right angle in our both triangles and measure of other two angles will be 90 degrees in both triangles by angle sum property of triangles.

Hypotenuse angle theorem states that two right triangles are congruent, if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle.

Therefore, by HA congruence triangle ABC is congruent to triangle DEF and option C is the correct choice.

Answer from: chantelljenkins2

Step-by-step explanation:

Given: ∠C, ∠F are right angles ∠'s

Then the given triangles in picture Δ ABC and ΔDEF are right triangles, such that the sides opposite to the right angles AB and and DE are hypotenuse of triangles Δ ABC and ΔDEF respectively.

Also it is given that AB = DE; ∠A = ∠D

Then by HA theorem ,

Δ ABC ≅ ΔDEF

HA Theorem says that if the hypotenuse and an angle of a right triangle are congruent to the hypotenuse and an angle of another triangle, then the two triangles are said to be congruent.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: $\sqrt{\frac{ {72x}^{16} }{ {50x}^{{{36} }}}} = \frac{ { \sqrt{72}x}^{ {16}^{ (\frac{1}{2}) } } }{ { \sqrt{50} x}^ {{36}^{ (\frac{1}{2}) } }}$ multiply exponents per exponent rules to get: $\frac{ { \sqrt{72}x}^{8} }{ { \sqrt{50}x}^{18} }$ remember you subtract exponents from the denominator and add exponents in the numerator so: $\sqrt{ \frac{72}{ 50}} \times ( {x}^{(8 - 18) } ) = \sqrt{ \frac{36}{25} } \times ( {x}^{ - 10} )$ simplify further: $\frac{6}{5} {x}^{ - 10} = \frac{6}{5 {x}^{10} }$ so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
