Angle g would be congruent/equal to itself because of verticals angles theorem. i hope that helped a bit
The slope is negative one
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
Hello! The answer to your question would be as followed:
<u><em>4.98 x 10^5 </em></u>
D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
