Answer:
x =
, y = 2
Step-by-step explanation:
using the tangent ratio and the exact value tan45° = 1 , then
tan45° =
=
= 1 , then
x = 
----------------------------------
using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
y =
×
=
= 2
Answer:
The answer for the first problem is B. The answer to the second problem is A.
Step-by-step explanation:
Explanation for first problem: Factor the equation and get (w+5)(w-4). Then multiply the numerator of the equation (w-3) by (w-4) and get w²-7w+12.
Explanation for second problem: Plug in the values of choice A., -2 and 4, and they cause the denominators to equal 0 which is against the rules or considered illegal.
Answer:
<u>(1/14)</u>
Step-by-step explanation:
(6/7)/(12) <u>6/7 as a fraction divided by a whole of 12</u>
(6/7)/(12/1)
(6/7)*(1/12)
(1/7)*(1/2)
(1/14)
