Answer:
The value of DC is 66.34.
Step-by-step explanation:
The triangles ABC and DCA are right angled triangles.
The straight line AC is a bisector for angles C and A.
The measure of ∠C is 30°.
Then the measure of angles BCA and ACD will be 15° each.
The measure of angle DAB is 150°.
Then the measure of angles DAC and BAC will be 75° each.
Now consider the right angled triangle ABC.
The measure of side AC is:
Consider the right angled triangle DCA.
The angle DAC measure 75°.
Using the trigonometric identities compute the value of Perpendicular DC as follows:
Thus, the value of DC is 66.34.
The answer:
radical number is sometimes called, irrational number. Radical number is inside the specific symbol √. For example, √a is called square root of a, for all value positive of the number a.
According to our case, there are five choices, among these, the numbers which can be called as radical are
3x√x²y , x√xy²,
proof:
3x√x²y = √9x²x²y= √9x²√x²y, and we know that √9x² = 3x, so √9x²√x²y= 3x√x²y
x√xy² =√x²xy² , and we know that √x² = x, so √x²√xy²= x√xy²
