Answer:
<h2>x = 20</h2>
Step-by-step explanation:
To find x we use cosine
That's
cos ∅ = adjacent / hypotenuse
From the question
The adjacent is x
The hypotenuse is 28
So we have
cos 43 = x / 28
x = 28 cos 43
x = 20.477
x = 20 to the nearest tenth

Answer:
Step-by-step explanation:
Given the simultaneous equation
2x - y = 11. Equation 1
6x – 3y = 15. Equation 2
Using elimination method
Multiply the coefficient of x in equation 1 (which is 2) to equation 2. Also, multiply the coefficient of x in equation 2 (which 6) to equation 1. By doing this we are going to eliminate x
2x - y = 11. × 6 Equation 1
6x – 3y = 15. ×2 Equation 2
12x-6y=66. Equation 3
12x-6y=30. Equation 4
Subtract equation 4 from 3
Then (12x-6y) - (12x-6y) =66 -30
0=36
Which is not possible
Then the system has no solution, it has no solution at all. Because 0 is not equal to 36. If has been 0 equals to 0, then we may many solutions for simultaneous equation.
Answer:

Step-by-step explanation:
using the cofunction identity
sin x = cos(90 - x), hence
sin75° = cos(90 - 75)° = cos15°
