Answer:
C. 57
Step-by-step explanation:
all triangles add up to 180. the tick marks show that ∠D and ∠ E are congruent so you do this and solve for x:
(4x + 1) + (4x + 1) + (5x - 4) = 180
13x - 2 = 180
13x = 182
x = 182/13
x = 14
4(14) + 1 = 57
Answer:
none of them are rational
Step-by-step explanation:
hope this helped you! :D
2x+9= 32
2x= 32-9
2x= 23
x= 23:2
x= 11.5
