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.

i can answer this question sweetie!

step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
