Answers:
Question 1:
second option : tan P = 35 / 12 and tan Q =12 /35
Question 2:
last option: sin A = 12 /13 and cos A = 5 / 13
Explanation:
In a right-angled triangle, special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Now, let's see what we have here
question (1):
Part (a):
θ = P
opposite = 35
adjacent = 12
tan P = opposite / adjacent = 35 / 12
Part (b):
θ = Q
opposite = 12
adjacent = 35
tan Q = opposite / adjacent = 12 /35
question (2):
Part (a):
θ = A
opposite = 12
hypotenuse = 13
sin A = opposite / hypotenuse = 12 /13
Part (b):
θ = A
adjacent = 5
hypotenuse = 13
cos A = adjacent / hypotenuse = 5 / 13
Hope this helps :)
Answer: Formula For Factoring Trinomials (when a =1)
It's always easaier to understand a new concept by looking at a
specific example so you might want to do that first. This formula works
when 'a' is 1. [ In other words, we will use this approach whenever the
coefficient in from of x2 is 1.
1) identify a,b, and c in the trinomial ax2 + bx+c
2) write down all factor pairs of c
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials

Answer: x=−1/2,4/3
Step-by-step explanation:
1. Split the second term in 6x^2−5x−4 into two terms.
6x^2+3x−8x−4=0
2. Factor out common terms in the first two terms, then in the last two terms.
3x(2x+1)−4(2x+1)=0
3. Factor out the common term 2x+1.
(2x+1)(3x−4)=0
4. Solve for x.
Ask: When will (2x+1)(3x−4) equal zero?
When 2x+1=0 or 3x-4=0
Solve each of the 2 equations above.
x=−1/2,4/3
