4 answers because there are 2 ys and 2xs
Answer:
x = 15 degrees
3 angles in triangle are 44, 44 and 92 degrees.
Step-by-step explanation:
When the lines are parallel the internal angles add up to 180 degrees. So:-
8x + 7 + 2x + 23 = 180
10x + 30 = 180
10x = 150
x = 15
In the triangle:-
The angle adjacent to 136 = 180 - 136
= 44 degrees. As 2 sides of the triangle are congruent the other base angle = 44 degrees also.
The third angle = 180 - 2(44) = 92 degrees
B and E are the correct answers
Answer:
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Step-by-step explanation:
Given the expression :
4(m + 3 + 5m)
Equivalent expressions include :
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Using algebaraic properties :
4(m + 3 + 5m)
We can expand :
4m + 12 + 20m
4m + 20m + 12
24m + 12
Hence,
4(m + 3 + 5m) = 24m + 12
Using Substitution:
Let m = 5
4(m + 3 + 5m)
4(5 + 3 + 5(5))
4(5 +3 + 25)
4(33)
= 132
12(2m + 1)
12(2(5) + 1)
12(10 + 1)
12(11)
= 132
