Step-by-step explanation:
Answer:
108° or Red
Step-by-step explanation:
This looks closest to a 108° angle.
108 - 7 = 101
101 ÷ 5 = 23
<em>x</em> = 23
Do the simple math for the rest of the angles...
Here is the math from where that leaves you...
127° (<em>b</em>) + 90° (<em>d</em>) + 136° (<em>e</em>) + 79° (<em>a</em>) + 108° (<em>c</em>) = 540°
P.S.
Rectangle answer must be 360° because 90° × 4 = 360°
Any additional vertices equals another 180° to the final number.
-7 + 56x = 105
56x = 105 + 7
56x = 112
x = 2
Answer:
3/20
Step-by-step explanation:
15 and 100 both have a common factor of <em>5</em>. To simply an expression, you have to get both the numerator (top number) and the denominator (bottom number) to be as low as possible (to make it so that both can't be divided anymore or don't have shared factors). We divide both sides by 5 (which still retains as an integer and has the same value) and so 15/3=5 and 100/5=20.
Have a nice day! :)
