The slope formula is m= y2-y1/x2-x1.
m= 4-0/2-5
m=4/-3
Therefore, 4/-3 is the slope.
Hello,
4+0j=4(cos 0+j*sin 0)
3+4j=√5(cos 53.1301...°+j*sin 53.130102...)
2-2j=2√2(cos 45°-j*sin 45°)
You haven't told us whether 9 and 12 are the two legs of the triangle, or whether the 12yd is the longest side.
<u>If the 9 and the 12 are the two legs, then</u>:
C² = A² + B²
C² = 81 + 144
C² = 225
C = <u>15 yd</u>
<u>If the 12 is the longest side, then</u>:
(12)² = (9)² + B²
B² = (12)² - (9)² = 144 - 81 = 63
B = √63 = <u>7.937</u>yd (rounded)

hope that helps</span>
