Angle Sum Theorem, thank you so much for the help, in advance! ​
daser333 [38]

Answer:

x=20°, and y is 90° btw

Step-by-step explanation:

This is an iscoceles triangle, since the base angles are equal and the altitude bisects one of the angles. 180 - 110 = 70, meaning the angles are 70 , 70 and 2x. We know that 70 + 70 + 2x = 180 from the angle sum theorem, so 140 + 2x = 180, and 40 = 2x. x = 20°

How to factorise 24x+3
yan [13]
The first thing to do is to work out the biggest number that goes into bother 24 and 3.  As the only that goes into three- other than 1- is itself, one can assume this is the number we are looking for.  

Next, divide bother numbers by 3. 
24 / 3 = 8
 3 / 3 = 1

You now take 3 out of the brackets, and leave 8 and 1. 24x / 3 = 8x. 

3(8x + 1)
