X=23 First, you have to subtract 12 by 12 to cancel it out. Next, you have to do the same thing to 20.05. 20.05 minus 12 is 8.05. All you have left is .35x. To get rid of the this you have to divide .35x by .35. Now all you have left is x. Finally you have to do the same thing to 8.05. 8.05 divided by .35 is 23. So, x=23
Answer:
The similarity postulate theorem is;
Similar - AA
Step-by-step explanation:
We are told that angle p is congruent to angle s, angle q is congruent to angle t.
Thus it is an AA similarity theorem because AA similarity theorem states that: If two angles in one triangle are congruent/respectively equal to two angles of another triangle, then the 2 triangles are similar.
For example, if we assume ΔABC and ΔDEF to be two triangles such that ∠A = ∠D and ∠B = ∠E. Then the two triangles are equiangular and thus they are similar by AA.
Before we do anything, we need to find out how fast we are going in the first place.
We know we are going 1.5 miles per minute and that there are 60 minutes in an hour, so we can find our speed in mph. All we have to do is multiply 60 and 1.5.
That gives us 90 mph.
Next, the problem says that we reduce our speed by 15 mph, so you would subtract 15 from 90.
That gives us 75 mph.
The last thing the problem says is that we reduce our speed by one third, so first we need to know what one third of 75 is. We can find that by dividing 75 by 3.
That gives us 25
But we aren't finished yet! We still need to subtract 25 from 75 to get our current speed. When we do this we get our final answer of...
50 mph

Given:
A figure of right triangle with terminal angle , base u, perpendicular v and hypotenuse r.
To find:
The value of .
Solution:
In a right angle triangle,
Substituting Perpendicular = v and hypotenuse = r in the above formula, we get
The value of is .
Therefore, the correct option is B.
