The 3 inside angles need to equal 180.
Subtract E from 180 to find the sum of the other two angles:
180 - 104 = 76
Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2
Angle D = 38
Probability red+green
first pick(red) : 7/10
2nd pick( green) : 1/10
the answer maybe like this
prob : 7/10+1/10 = 8/10 =4/5
Answer:
x = ± 10
Step-by-step explanation:
Given
x² - 100 = 0 ( add 100 to both sides )
x² = 100 ( take the square root of both sides )
x = ± ← note plus or minus, hence
x = ± 10
Answer:
145⁰
Step-by-step explanation:
180 minus 73⁰ plus 62⁰
which is 180 minus 135
145⁰
Answer:
No, it's not a solution.
Step-by-step explanation:
-2 + 4(3) = 4
-2 + 12 = 10
-2 + 3(3) = 1
-2 + 9 = 7
