Find the distance between the points given. (3, 4) and (4, 7) √(10) 3 2√2
Tom [10]

Answer:

Step-by-step explanation:

givens

x1 = 3

x2 = 4

y1 = 4

y2 = 7

formula

d = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )

solution

d = sqrt( (3 - 4)^2 + (4 - 7)^2 )

d = sqrt ( 1 + 3^2)

d = sqrt( 1 + 9)

d = sqrt( 10)

Find the measure of BE step by step<br>​
Whitepunk [10]

Answer:

BE = 49 cm

Step-by-step explanation:

Use Pythagorean theorem

(hypotenuse)² = (base)² + (leg)²

ΔDEF,

DE² + EF² = FD²

DE² + 63² = 65²

DE² + 3969 = 4225

              DE² = 4225 - 3969

              DE² = 256

             DE = √256 = √(16*16)

DE = 16 cm

ΔCBD,

BC² + BD² = CD²

56² +BD² = 65²

3136 + BD² = 4225

           BD² = 4225 - 3136

           BD² = 1089

          BD = √1089 = √(33*33)

BD = 33 cm

BE = BD + DE

    = 33 + 16

BE = 49 cm
