Find the value of x.

Artemon [7]

${5}^{2} + {x}^{2} = {8}^{2}$

$25 + {x}^{2} = 64$

Subtract both sides 25

$25 - 25 + {x}^{2} = 64 - 25$

${x}^{2} = 39$

Thus :

$x = \sqrt{39}$

$x = 6.245$

Daniel created an intersection with his race track. One of the angles at the intersection is 55°. What are the three other angle

melomori [17]

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.

Find the 12th term of the sequence -15,-9,-3, 3

Reika [66]

First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51
