60+60 is 120. subtract 180-120, which leaves you with 60. divide 60 by 5, which 12. x = 12. please mark brainliest and have a good day
Answer:
x = 12
Step-by-step explanation:
the sum of inner angles in a triangle is 180
then 180 = 60 + 60 + 5x
after that 5x = 60, x= 12.
60 f+80=287

-11 2/3 x (-4 1/5) =
negative times negative = positive
Change the mixed numerals into fractions.
= 35/3 × 21/5
Multiply the numerators together. Multiply the denominators together.
= (35 × 21)/(3 × 5)
Simplify.
= (7 × 5 × 7 × 3)/(3 × 5)
Divide the numerator and denominator by 3 and by 5.
= 7 × 7
= 49
