The unknown angle is <em>80°. </em>There is a <em>simple</em> formula to figure out the unknown angle. Add the angles and then subtract the sum of the two angles from 180. You would do this because the sum of interior angles of a triangle is 180°.
<em>x=180°-(angle 1 + angle 2)</em>
Answer:

Answer:
1/6
Step-by-step explanation:
an even number has a 1/2 chance of being rolled and a number greater than 4 has a 1/3 chance of getting rolled. multiply 1/2 and 1/3 together and you get 1/6 for your answer.
Answer:
y= -3x + 8
Step-by-step explanation:
Put -2x + 6y = -4 into slope-interceltp form
Take the negative reciprocal of the slope.
Use this reciprocal in point-slope form
and you have,
= y= -3x + 8
<em>(EDITED)</em> Steps:
2x+6y = -4
6y=2x - 4
y= 1/3x + 2/3
if two lines are perpendicular,
m1 * m2 + -1
1/3 * m2 = -1
m2 = -3
the line perpendicular to this line is
y = -3x + k ; k ∈ R
the line passes through the point (5,-7)
so,
-7 = -3. (5) +k
-7 = -15 + k
k = 8
∴the equation of a line that passes through the point (5,-7) and is perpendicular to the line -2x+6y=-4 is
y= -3x + 8
Hope this helps, have a nice day/night! :D
The answer to this question would be true.
An odd number wouldn't have any 2 in their factor because it is the definition of odd number, can't be divided by 2. Since they have no probability of having factor 2, then their GCF would not become an even number.
