Answer:
Sin A = 0.6896
Cos A = 0.7241
Tan A = 0.9524
Step-by-step explanation:
Using SOH-CAH-TOA
Sin A = Opposite / Hypotenous
= 20 / 29
= 0.6896
Cos A = Adjacent / Hypotenous
= 21 / 29
= 0.7241
Tan A = Opposite / Adjacent
= 20 / 21
= 0.9524
Answer:
C
Step-by-step explanation:
I used a calculator lol
1. To solve this problem you must apply the proccedure shown below:
2. When you multiply two polynomials, you must apply the distributive property and multiply the coefficients and add the exponents. For example:
(x)(x^2)
The coefficients of both terms are 1 and the sum of the exponents is 3= (1+2=3)
Therefore:
(x)(x^2)=x^3
3. Keeping that on mind, when you multiply the polynomials shown in the figure attached, the result is:
(x-6)(x^2+2x-4)
x^3-4x^2-16x+24
