3(x-2)=22-x how many solutions
1 answer:
There is only one solution, which is: x = 7
Steps to solve:
Use the distributive property to multiply anything inside the parenthesis by 3.
3x - 3 x 2 =
3x - 6 = 22 - x
Move the variable on the right side to the left side and change the sign.
3x + x - 6 = 22
Move the constant on the left to the right and change its sign.
3x + x = 22 + 6
Gather like terms.
4x = 22 + 6
Add the numbers.
4x = 28
Divide both sides of the equation by 4.
x = 7

<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
Answer: 122°
Step-by-step explanation:
When an angle is supplementary to each other , it means the angle measures to 180°.
Now since one of the two angles is 58°, therefore, the other angle will be
180° - 58°
= 122°
