Answer:
12 ft
Step-by-step explanation:
It is sometimes helpful to start from what you are given and see what develops.
Here, angle B is 30°. That means angle CAB is 60° (the acute angles of a right triangle are complements). AL bisects that 60° angle, meaning two things:
- ΔALC is a 30°-60°-90° triangle, so you know its side ratios
- ∠LAB = 30°, so ΔALB is isosceles and AL = LB
The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2, so AL is 2 times the length of CL.
AL = 2 × (6 ft) = 12 ft
We know that AL = LB, so LB = 12 ft.
Answer:
if 5 people =1 hour. which is 60 minutes.
so 8people.52 minutes ...it wont take hours .since an hour is 60 min.
Answer: what are steps 1-2? may i have the question?
Step-by-step explanation:
Answer:
10th term of the sequence 64,16,4... = 1/4096
Step-by-step explanation:
Points to remember
nth term of GP is given by.
Tₙ = ar⁽ⁿ⁻¹⁾
Where r is the common ratio and a is the first term
<u>To find the 10th term of given GP</u>
It is given that,
64, 16, 4,......
a = 64 and 6 = 1/4 Here
T₁₀ = ar⁽ⁿ⁻¹⁾
= 64 * (1/4)⁽¹⁰⁻¹⁾ = 64 * (1/4⁹)
= 4³/4⁹ = 1/4⁶ = 1/4096
Answer:
Neither
Step-by-step explanation:
142 + 56 = 198º
Complimentary = 90º
Supplementary = 180º
