Given: mtrv = 60° mtrs = (4x)° prove: x = 30 what is the missing reason in step 3? substitution property of equality angle addition postulate subtraction property of equality addition property of equality

Angle addition postulate.

Explanation: If and

here, if we have to prove x=30

If there is a condition that TR is a line which meets with the line segment VS at point R then by the Angle addition postulate,  we can say that ⇒

But,

In option (1) substitution property of equality

If there is condition that  

then we can use  substitution property of equality,

And, in this case ⇒

which is wrong. So, we can not use this property here.

In option (3) subtraction property of equality

There is no use of this property to find the value x.

In option (4) addition property of equality

There is no use of this property to find the value x.

The final answer is 3x3+6x2+8x+24+47x−2mark me brainliest

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
