Answer:
D. (x2 - x1)2 + (y2 - y1)2
Step-by-step explanation:
We can use the Pythagorean Theorem or Distance formula to solve this problem. JK = x2 - x1 and LJ = y2 - y1. To find LK, you square the two legs, add them together and take the square root. The solution is
(x2 - x1)2 + (y2 - y1)2
.

The formula for finding equation of line in point - slope form is given as :
substituting into the formula , we have
Answer:
false
Step-by-step explanation:
Add the whole numbers 4 + 3 = 7
Add the fractions 1/2 + 1/4
Rewrite 1/2 to have a common denominator with 1/4
1/2 = 2/4
Now add 2/4 + 1/4 = 3/4
The answer would be 7 3/4
Answer:
2√2
Step-by-step explanation:
<u>By </u><u>using </u><u>trigonometry,</u>
sin 45° = x/4
x = 4sin 45°
x = 2√2
<u>By </u><u>using </u><u>Pythagorean</u><u> </u><u>theorem</u><u>,</u>
Since you know that it is an isosceles triangle and it's also a right-angled triangle,
4² = x² + x²
16 = 2x²
x² = 8
x = √8
= 2√2
