tan ACH = opp/adj = AH / CH

We know CH we just need AH.

We have three similar triangles.  Each has a right angle and shares an acute angle with ABC, so similar by AA.

Let's get the order right,

ABC ~ HBA ~ HAC

It looks like from the last two we get an equal ratio equation involving AH, BH, and CH.

HBA ~ HAC

HB/HA = HA/HC

HB×HC = HA²

HA² = 4×8 = 32

HA = √32 = 4√2

tan ACH= AH / CH = 4√2 / 8 = √2/2

Answer:   D)  √2/2

5. Which polynomial is equal to (x5 + 1) divided by (x + 1)?
Mkey [24]

Answer:

B  x^4-x^3+x^2-x+1

Step-by-step explanation:

Given,

Dividend = (x^5+1)

Divisor = (x+1)

Step 1: First The dividend is (x^5+1) and Divisor is (x+1) when divided first time the quotient will be x^4 and remainder will be -x^4+1

Step: 2 Now the new dividend is -x^4+1 and Divisor is (x+1)  when divided the quotient will be x^4-x^3 and remainder will be x^3+1

Step: 3 Now the new dividend is x^3+1 and Divisor is (x+1)  when divided the quotient will be x^4-x^3+x^2 and remainder will be -x^2+1

Step: 4 Now the new dividend is -x^2+1 and Divisor is (x+1)  when divided the quotient will be x^4-x^3+x^2-x and remainder will be x+1

Step: 5 Now the new dividend is x+1 and Divisor is (x+1)  when divided the quotient will be x^4-x^3+x^2-x+1 and remainder will be 0.

Hence When the polynomial (x^5+1) is divided by  (x+1) the answer or quotient will be equal to  x^4-x^3+x^2-x+1 and remainder will be 0.
