Thought i answered this one already
a)
m∠2 = 180 - m∠1 - <span>m∠3
</span><span>m∠2 = 180 - 79 - 27
</span><span>m∠2 = 74
b)
</span><span>m∠4 = m3 = 27 (vertical angles)
</span>
c)
m∠6 = 180 - m∠4 -<span>m∠5
</span><span>m∠6 = 180 -27 - 82
</span><span>m∠6 = 71</span>
For ax2 + bx + c = 0, the value of x is given by: For the Quadratic Formula to work, you must have your equation arranged in the form "(quadratic) = 0". Also, the "2a" in the denominator of the Formula is underneath everything above, not just the square root. And it's a "2a" under there, not just a plain "2".
A tangent line is always perpendicular to the radius that shares the point of tangency. In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.
12=8-5x move the terms
5x=8-12 calculate
5x= (-4) divide both sides
<h2>x= -4/5 or decimal form x= -0.8</h2>
