Help me on isosceles and equilateral triangles problems. Find the value of x in the triangle shown below.​
trapecia [35]

Answer:

  x° = 61°

Step-by-step explanation:

Both of the "unknown" angles in the triangle are equal, since their opposite sides have equal lengths. (The triangle is isosceles.) The sum of angles in a triangle is 180°, so we have ...

  58° + x° + x° = 180°

  2x° = 122° . . . . subtract 58°, collect terms

  x° = 61° . . . . . . . divide by 2

A factory purchased a machine for $35,000. the value of the machine depreciates at a rate of 10% each year.
Dafna1 [17]
If you're finding the future value: P=35,000(1-.1/1)^1. this is assuming you want to know the value of it after one year. if you want it to be more years, like two : P=35,000(1-.1/2)^2. When entered into the calculator enter it like so : 35,000(1-(.1/1))^1. when that's done you end up with $31,500. that's the machine's worth. it lost 3,500. 35,000-31500.
