Answer:
Final factor is (x-9)(x+4)
Step-by-step explanation:
Given expression is .
Now we need to factor that expression
Find two numbers whose product is -36 and sum is -5.
Two such numbers oare -9 and +4. So we get:
Hence final factor is (x-9)(x+4)
Answer:
Therefore 'x' is equal to 65.4°
Step-by-step explanation:
In Right Angle Triangle ABC
∠ B = 90°
AC = Hypotenuse = 12
CB = Adjacent Side = 5
To Find:
∠ C = x
Solution:
In Right Angle Triangle ABC Cosine Identity we have
Substituting the values we get
Therefore 'x' is equal to 65.4°
