Those angles have to be equal
so 3x-25=6x-80
3x-6x=-80+25
-3x=-55
x=55/3
Answer:
t=11.9
Step-by-step explanation:
960=420(2)^t/10
2.28571429=2^t/10
add log to both sides
log(2.28571429)=10
t log(2)
divide by log 2
1.19264508= 10
/t
10(1.19264508)
11.926450779=t
Answer:
Step-by-step explanation:
we need that theta angle .. soooo.... use SOH CAH TOA to remind yourself how the trig functions fit on the triangle.....
since we have all 3 side any one of the above trig functions would work. as a side note.. Tan is limited to the 1st quadrant on a calculator.. so maybe Cos is a good choice. although it would work in this case....
sooo ....
Cos(Ф) = Adj / Hyp
Ф = arcCos( 24 /25)
Ф ≈16.26°
I don't have csc on my calculator but I know that 1/sin = csc sooo
csc(16.26)=1/sin(16.26) ≈ 3.57
sec(16.26)= 1/cos(26.26) ≈ 1.041
cot(16.26) = cos(16.26) / sin(16.26) ≈3.476
Answer:
<u>The simplest system:</u>
<u>Solve by eliminating y:</u>
- x² = x
- x(x - 1) = 0
- x₁ = 0
- x₂ = 1
<u>Then the value of y:</u>
