Answer:
<h2>58°</h2>
Step-by-step explanation:
We will use the tangent function since we know the opposite and adjacent sides.
Tangent = opposite/adjacent
Tan(e) = 16/10
Tan(e) = 1.6
Use the inverse tangent function to find the angle.
Arctan (1.6) = 57.9946168
Rounding this we get: 58°
Answer:
2 and 1/5 is greater than 2.15
Step-by-step explanation:
This is true because 1/5 is equal to .20 which is greater than .15
Answer:
For k = 6 or k = -6, the equation will have exactly one solution.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
If 
, the equation has only one solution.
In this problem, we have that:
So
We will only have one solution if . So
For k = 6 or k = -6, the equation will have exactly one solution.
Answer:
x = 6 and y = - 6
Step-by-step explanation:
- 4 x - 2 y = -12.......equ No 1
4 x + 8y = - 24.......equ No 2
Adding equ No 1 and equ No 2
6 y = - 36
∴ y = - 6
substitute y = - 6 in equ No 2
4 x + 8 y = -24
4 x + 8 ×( -6) = - 24
4 x - 48 = -24
4 x = -24 + 48
4 x = 24
∴ x = 6
x = 6 and y = - 6
