If triangle TSR is similar to triangle TNM, what is the length of x?
kolezko [41]
X would equal half of 70 because alternate exterior angles are congruent- and 120 is half of 240.

So,

70/2= 35

x would equal 35.

I hope this helps!

Use the digits 0-9, find out how many 4 digit numbers can be configured based on the stated conditions:
Alexeev081 [22]
A) On the first place we can put 9 digits, on the second 9, on the third place 8 and on the last place 7 ( because no digits can be repeated ):
9 · 9 · 8 · 7 =4536 numbers
b) There are 5 odd digits can be repeated. So:
5 · 10 · 10 · 5 = 2500 numbers
c) On the first place we can put:5,6,7,8,9 (5 digits) On the last place is just one (0), because the number must be divisible by 10:
5 · 10 · 10 · 1 = 500 numbers
d) on the first place we can put 2 digits ( 1, or 2 - there are no 4-digit numbers starting with 0). The last digit must be even, but the order can be:
X - odd - odd - even           2 · 5 · 4 ·  5 = 200
X - odd - even - even         2 · 5  · 5 · 4 = 200
X - even - odd - even         2 · 5  · 5 · 4 = 200
X - even - even - even       2 · 5 ·  4 · 3 = 120 
Finally: 200+ 200 + 200 + 120 = 720 numbers
