Question

6. The diagram shows triangle ABC with vertices A(-2, 1), B(1,1) and C(3,4) Find the length of AC, giving your answer correct to 2 decimal places. ​

Answer 1

Answer:

3.16 units

Step-by-step explanation:

Using Distance formula

$\sqrt{ {(3 + 2)}^{2} + {(4 - 1)}^{2} } = \sqrt{1 + 9} = \sqrt{10} = 3.16 \: units$

Answer 2

Answer:

use the distance formula

Step-by-step explanation:

AC=√(3-(-2)²+(4-1)²

= √(3+2)²+3²

= √5²+3²=√25+9=√34
