Given: mTRV = 60° mTRS = (4x)° Prove: x = 30 What is the missing reason in step 3? substitution property of equality angle addit

mihalych1998 [28]

Answer: Angle addition postulate.

Explanation: If $\angle TRV= 60^{\circ}$ and $\angle TRS=4x^{\circ}$

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 $\angle TRV+\angle TRS=180^{\circ}$ ⇒ $x=30^{\circ}$

But,

In option (1) substitution property of equality

If there is condition that $\angle TRV=\angle TRS$

then we can use substitution property of equality,

And, in this case $4x^{\circ}=60^{\circ}$ ⇒ $x=15^{\circ}$

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.

7.1x10^-2 as an ordinary number

Sonja [21]

Hey there,

So let's start off with one part of this equation . . .

$10^{-2}$ would be 0.01.

So, we have 0.01 has our answer (so far).

Then we would do 7.1 × 0.01, this would give us . . .

0.071.

Your correct and final answer would be $\boxed{0.071}$

Hope this helps you!

I NEED HELP PLEASE! Jenny's birthday cake is circular and has a 30 cm radius. Her slice creates an arc of with a central angle o

dybincka [34]

Ok, so if the angle is 120 degrees, its one third of the full cake (which is 360 degrees). So the area of the whole circle (worked out with area = pi * r^2 where r is 30) gives 900*pi, and so one third of that (because her slice is one third) is 300pi.

Hich expression is equivalent to -4(7 - 2m) + 11m?

Sholpan [36]

Answer:

$- 4(7 - 2m) + 11m \\ = - 28 + 8m + 11m \\ = \boxed{19m - 28}$

<em><u>Expression (19m-28) is equivalent to -4(7 - 2m) + 11m.</u></em>
