Answer:
D
Step-by-step explanation:
Well there's a theorem about the sum of the interior angles of a triangle that says that the sum is equal to 180°
so we have
so it's option D

0.111111
Step-by-step explanation:
Answer:
1/16
Step-by-step explanation:
The spinner has 8 equal parts.
The probability of spinning a 5 is: 1/8 (because there is only one 5 to choose and 8 total parts that could be landed on).
The probability of spinning an even number is: 4/8 = 1/2 (because there are 4 even numbers, 2 4 6 8, and there are 8 total parts that could be landed on).
Now, we need to multiply these two probabilities together:
(1/8) * (1/2) = 1/16
Hope this helps!
3x-11=x+23
-x -x
2x-11=23
+11 +11
2x=34
x=17
3(17)-11 17+23
=40 =40
explanation ;
you would equal them because they are congruent . & you substitute x for 17 in each equation to find out the degrees of both of the angles :)
