Need help with some practice questions since all are different types I'm asking alot sorry!​
sasho [114]

Answer:

Yes

Step-by-step explanation:

If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:

ECM = 3x + 15

becomes

90 = 3x + 15

75 = 3x

25 = x

ACE = 4x - 10

becomes

90 = 4x - 10

100 = 4x

25 = x

Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees

First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
