See attached picture for better understanding of the problem. In the problem, the given values are the following:
hypotenuse = length of the ladder
adjacent = base of the ladder to base of the wall
Solving the angle x, we have the solution as below:
cos x = adjacent / hypotenuse
cos x = 91 / 350
x = 74.93°
The answer is 74.93°.
Infinite number of solutions...means it will be the same line.
you have probably heard about equivalent fractions like 1/2 = 2/4...and if u reduce 2/4, it equals 1/2. Well...there are also equivalent equations. They can also be reduced.
3y = 2x - 9 cant be reduced, but u can make an equivalent equation by multiplying it all by a number.Any number.
lets try 2...
2(3y = 2x - 9) =
6y = 4x - 18...this is an equivalent equation....the same line..infinite solutions.Notice that u can reduce it by dividing everything by 2 which would equal 3y = 2x - 9....so u see, it is like equivalent fractions....kind of...lol
or multiply it by 3
3(3y = 2x - 9) =
9y = 6x - 27....this is also equivalent.....so this is an answer as well
and u can multiply it by 4 and get another equivalent equation..or 5, or 6....and so on...
make any sense ?? Just remember, to get the result of infinite solutions, the equations have to be equivalent
Sheila Total:: 6x
<span>Sherri Total:: 5(x+10) = 5x+50
</span><span>(a) Write an equation. Let x represent the amount of one of Sheila’s deposits.
6x = 5x+50
</span><span>(b) Solve the equation. Show your work.
x = 50
</span><span>(c) Check your solution. Show your work.
6*50 = 5(50+10)
300 = 5*60
300 = 300</span>
<span>(d) State the solution in complete sentences.
I'll leave that to you.

Answer:
An equation is a mathematical statement that two expressions are equal. The solution of an equation is the value that when substituted for the variable makes the equation a true statement.
