Triangle ABC is congruent to triangle DEF .
2 answers:
Answer:
Step-by-step explanation:
Alright lets get started.
Please refer the diagram I have attached.
For both triangles should be congruent, adjacent sides should be congruent or adjacent angles should be same.
BC = EF Which is not matching with our option.
AC = DF Which is not matching with our option.
angle B = angle E Which is not matching with our option.
angle A = angle D adjacent angle, whiich is matching with our option.
Hence angle A = angle D for both triangles should congruent. : Answer

Answer:
Step-by-step explanation:
(a - b)(a +b) = a² - b²
1 - Sin² A = Cos² A
2) Sec² A - Tan² A = 1
3) LHS = Cosec² A + Cot² A
= Cosec² A + Cosec² A - 1
= 2Cosec² A - 1 = RHS
Answer: The difference cannot be found because the indices of the radicals are not the same.
Step-by-step explanation:
To find the difference you need to subtract the radicals. But it is important ot remember the following: To make the subtraction of radicals, the indices and the radicand must be the same.
In this case you have these radicals:
You can observe that the radicands are the same, but their indices are not the same.
Therefore, since the indices are different you cannot subtract these radicals.
