Answer:

+4.245

Step-by-step explanation:

Before you can find the square root of x^2, you have to EVALUATE

64+49-2(8)(7)cos32, and THEN take the square root of the result:

64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) =  113 - 94.981 = 18.019

Then x^2 = 18.019.

Find the square root of 18.019:  It is +4.245.  A negative result here would make no sense.

In a triangle the measurements of the angles are x°, ( x + 6)°, (2x + 10)°, and the sum of the three angles of a triangle is 180
34kurt

Answer:

largest angle = 92°

Step-by-step explanation:

Since the measurement of the angles are;

x°, ( x + 6)°, (2x + 10)°

And we know that sum of angles in a triangle is 180. Thus;

x + (x + 6) + (2x + 10) = 180

x + x + 6 + 2x + 10 = 180

4x + 16 = 180

4x = 180 - 16

4x = 164

x = 164/4

x = 41°

The other two angles will be;

(41 + 6)° and (2(41) + 10)°

Which gives;

47° and 92°

So,largest angle = 92°

I need help ASAP <br> Show your work: x - 8 = 12
choli [55]

Answer:

x = 20  

Step-by-step explanation:

x - 8 = 12                          Add 8 to both sides

x -8 + 8 = 12 + 8               Add -8 and 8; add 12 and 8

x = 20
