Answer:
If KE = OS then we can deduce that the trapezoid is constructed of 3 equilateral triangles and thus we can easily work out the angles.
OSK = 60
SKE = 120
KEP = 120
EPO = 60
We can also easily work out the perimeter since we can deduce that PE = SK = KE and thus the perimeter is 5 * 8 = 40
Answer:
x = 5 and y = 8.7
See attached image for working
Step-by-step explanation:
Since it's a right angle triangle you can use sin and cos.
Answer:
I believe that the value of the variable is C: 50.
And Y = 180 - 50 = 130.
Good Luck!
Answer:
-23
Step-by-step explanation: You have to combine like terms first:
-3.8x -5.9x =223.1
-9.7x = 223.1
Then divide om each side of the equation by -9.7.
-9.7x/-9.7 = 223.1/-9.7
x =- 23
Answer:
a) -4
b) 2
Step-by-step explanation:
a) f(-2) = 3*-2 + 2 = -4
b) f(x) = 8
3x + 2 = 8
3x = 8 -2
3x = 6
x = 6/3
x = 2
