Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,
Also,
Comparing both we get,
It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
Answer:
2(3x - 4)(3x + 4)
Step-by-step explanation:
Factorizing the below expression requires factoring common term.
Obviously 2 is common to both 18 and 32. Thus, the answer is:
=2(3x - 4)(3x + 4)
