Answer:

SAS

Step-by-step explanation: every triangle contains a total of 180 degrees if you substract 180 by 60+70(which is 130) you would get 50 degrees which is the exact degree missing in the first triangle, so after confirming that both triangles have an equal degrees on each side the answer would be SAS (which stands for Side-Angle-Side), SAS is the answer you would give to triangles that are congruent(equal)

Celebrity A has 400 followers on social media and is gaining 75 followers each day. Celebrity B has 1,000 followers on social me

MariettaO [177]

It takes 6 days for both of them to have same number of followers

<em><u>Solution:</u></em>

Let "x" be the number of days

<h3><u>Case 1:</u></h3>

<em><u>Celebrity A has 400 followers on social media and is gaining 75 followers each day</u></em>

We can frame a equation as:

Celebrity A : 400 + 75(number of days)

Celebrity A : 400 + 75x --------- eqn 1

<h3><u>Case 2:</u></h3>

<em><u>Celebrity B has 1,000 followers on social media, but is losing 25 followers a day</u></em>

We can frame a equation as:

Celebrity B : 1000 - 25(number of days)

Here we use negative sign to denote losing of followers

Celebrity B : 1000 - 25x --------- eqn 2

For both of them to have same number of followers, eqn 1 must be equal to eqn 2

$400 + 75x = 1000 - 25x\\\\\text{Solve the above equation for x}\\\\75x + 25x = 1000 - 400\\\\\text{Combine the like terms }\\\\100x = 600\\\\x = 6$

Thus it takes 6 days for both of them to have same number of followers
