Find the measure of angle 7 Measure of angle 7= 2x + 15 Measure of angle 8= 3x

1 answer:

7 0

Assuming ∠6 and angle ∠8 are vertical angles, then
m∠6 = m∠8 
m∠6 + m∠7 = m∠7 + m∠8 = 180 

2x + 15 + 3x = 180 
5x = 165 
x = 33 

m∠7 = 2(33)+15 = 81 
m∠8 = 3(33) = 99 

m∠6 = m∠8 = 99

An archaeologist at a dig sets up a coordinate system using string. Two similar artifacts are found one at position (1, 4) and t

myrzilka [38]

Given:

Positions of two artifacts are at points (1, 4) and (5, 2).

To find:

The distance between these two artifacts.

Solution:

Distance formula: The distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using distance formula, the distance between two points (1, 4) and (5, 2) is

$d=\sqrt{(5-1)^2+(2-4)^2}$

$d=\sqrt{(4)^2+(-2)^2}$

$d=\sqrt{16+4}$

$d=\sqrt{20}$

$d=4.4721359$

Round to the nearest tenth of a unit.

$d\approx 4.5$

Therefore, the distance between two artifacts is 4.5 units.
