The "distance formula" an extension of the Pythagorean Theorem is:
d^2=(x2-x1)^2+(y2-y1)^2 in this case:
d^2=(-8-7)^2+(-9--1)^2
d^2=(-15)^2+(-8)^2
d^2=15^2+8^2
d=√(15^2+8^2)
So the answer is 15^2+8^2
Answer:
c =9.7 cm
Step-by-step explanation:
Law of sines:
sin (82) / c = sin(55) / 8
0.9903 / c = 0.8192 / 8
c = 0.9903 * 8 / 0.8192
c =9.7 cm
Answer:
1: 80 (Vertical angles congruent)
2: 70 (Vertical angles congruent)
3:
4: 110 (Straight angle w/ angle 2, 180-70 {known variable})
5: 90 (Right angle)
6: 90 (Right angle)
7: 20 (180-90-70 (unmarked angle opposite 4)
9:
10:
Y=ax+b
A=y/x
= 192-96/4-2
= 96/2
=48
So y=48x+b
Lets replace y and x
96=48.2+b
B= 96-96
=0
So y=48x
