Lena [83]3 years ago
6 0

Answer:

2) d= 2 sqrt 13

3) d= sqrt 10

Step-by-step explanation:

Question 2.

(3,0) and (9,4)

d = sqrt [(4-0)^2 + (9-3)^2]

d = sqrt (16 + 36)

d = sqrt 52

d = 2 sqrt 13

Question 3.

(0,-7) and (- 1,-4)

d = sqrt [(-1-0)^2 + (-4- -7)^2]

d = sqrt [ (-1)^2 + (3)^2]

d = sqrt (1+9)

d = sqrt 10

Please help me. It’s geometry
Verizon [17]

Option 3:

m∠ABC = 66°

Solution:

Given \overline {F A D} \| \overline {E H C} and ABH is a transversal line.

m∠FAB = 48° and m∠ECB = 18°

m∠ECB = m∠HCB = 18°

<u>Property of parallel lines: </u>

<em>If two parallel lines cut by a transversal, then the alternate interior angles are equal.</em>

m∠FAB = m∠BHC

48° = m∠BHC

m∠BHC = 48°

<u>Exterior angle of a triangle theorem: </u>

<em>An exterior angle of a triangle is equal to the sum of the opposite interior angles.</em>

m∠ABC = m∠BHC + m∠HCB

m∠ABC = 48° + 18°

m∠ABC = 66°

Option 3 is the correct answer.

A wire is (7x – 3) meters long. A length of (3x – 4) meters is cut for use(a) How much wire is left?
ipn [44]

Answer:

The amount of wire left is 4x + 1

Step-by-step explanation:

Initially, the wire is (7x - 3) meters long.

A length of (3x - 4) meters is cut.

How much wire is left?

Initial amount subtracted by the amount that is cut. So

(7x - 3) - (3x - 4) = 7x - 3 - 3x + 4

We combine the like terms

7x - 3x - 3 + 4 = 4x + 1

The amount of wire left is 4x + 1
