Answer: 130</h3>
Explanation:
Let x be the unknown angle we want to find.
Let y be adjacent and supplementary to x. This means x+y = 180
Let z also be adjacent and supplementary to x. So x+z = 180 also
Subtracting the two equations leads to y-z = 0 and y = z. So effectively we've proven the vertical angle theorem.
Since the supplementary angles to x add to 100, we know that y+z = 100. Plug in y = z and solve for z
y+z = 100
z+z = 100
2z = 100
z = 100/2
z = 50
Therefore,
x+z = 180
x+50 = 180
x = 180-50
x = 130
Answer:
of the number is X, 16 = 1 + (2/10)×X - 8
Here is the answer OwO:
A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.
Here is the explanation/work OwO:
<u><em>Switch sides.</em></u>
c^2=12^2+9^2
<u><em>12^2=144</em></u>
c^2=144+9^2
<u><em>9^2=81</em></u>
c^2=144+81
<u><em>Add the numbers: 144 + 81 = 225</em></u>
c^2=225
<u><em>For x^2 = f(a) the solution is √f(a)</em></u>
c = 15
Therefore, your answer will be 15.
