Put it in the form 

ax^2 + bx + c = 0 

use the quadratic formula

x =  [ -b + sqrt( b^2 - 4 ac )  ] / 2a


x =  [ -b - sqrt( b^2 - 4 ac )  ] / 2a

7v^2 - 7v - 22 = 0

a = 7 
b = -7
c = -22

v = [  7 + sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7  = 2.34

v = [  7 - sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7  = -1.34

Find a.<br> Round to the nearest tenth:<br> 2 cm<br> с<br> 150<br> 1050<br> a =<br> = [? ]cm
VLD [36.1K]

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm
