Given: bisects ∠BAC; AB = AC Which congruence theorem can be used to prove △ABR ≅ △ACR?

astraxan [27]

Answer: SAS

Step-by-step explanation:

Here ABC is a triangle, In which angle BAC is bisected by line AR where, $R\in BC$ .

Thus in triangles ABR and ACR,

AB= AC ( given)

Therefore $AB\cong AC$

$\angle BAR\cong \angle CAR$ ( by the property of angle bisector)

And, $AR\cong AR$ (reflexive)

Thus by SAS postulate,

△ABR ≅ △ACR.

Therefore, Option D is correct.

11. The sales tax rate is 6.9%

Norma-Jean [14]

Answer:

40.1%

Step-by-step explanation:

I am assuming that 192 is in 100%.

100% = 192

I then represent the value that we are looking for with $x$ .

x% = 77

By dividing both equations (100% = 192 and x% = 77) and remembering that both left hand sides of BOTH equations have the percentage unit (%).

$\frac{100}{x} = \frac{77}{192}$

Now, of course, we take the reciprocal, or inverse, of both sides:

$\frac{x}{100} = \frac{7}{192}$

x = 40.1%

Thus making the answer: 40.1% of 192 is 77.
