Answer:
C
Step-by-step explanation:
the ratios of corresponding sides are in proportion
that is the outer triangle and the inner triangle
[tex]\frac{x}{30}[/tex] = [tex]\frac{88}{44}[/tex] = 2 ( multiply both sides by 30 to clear the fraction )
x = 30 × 2 = 60
Answer:
C. 60
Step-by-step explanation:
I just saw that 44 + 44 equals 88 and compared those two sides, I knew it couldn't be 88, so that's out. Then, I saw that the side, 21 + 21, was shorter than the unknown side and that ruled out 42 and 30. 60 is the only one that is left and makes sense.
