Since the lines are perpendicular the opposite angle of labeled is also 60° and so would the two angles on the the lower just opposite way therefore 8x-4=60
-4 -4
8x=56
/8 /8
X=7
<span>Megan
went to beach 34 times last summer.
June = x
July = 6 * june
August = 2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>

Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
I believe that would equal 65/21
hope that helps!
