Hello! answer: 40
Step-by-step explanation:
This is a supplementary angle meaning it will have a total of 180 degrees 4 × 40 = 160 and when you add that with the other angle 20 you get 160 + 20 = 180 therefore x must by 40 HOPE THAT HELPS!
<span>let y = sec^2 ( pi x )
y' = 2 sec ( pi x ) sec( pi x ) tan ( pi x ) pi
y' = 2pi sec^2 ( pi x ) tan ( pi x )
y''= 2pi sec^2 ( pi x ) * sec^2 ( pi x ) * pi + 2pi tan ( pi x ) * 2pi sec^2 ( pi x ) tan ( pi x )
y'' = 2 pi^2 sec^4 ( pi x ) + 4 pi^2 sec^2 ( pi x ) tan^2 ( pi x )</span>

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
Answer:
Measurements were needed for multiple things, such as agriculture, construction, and trade. Also, many areas developed their own systems for measuring objects making it difficult as people from different places had different results. Eventually, the same system was adopted by the majority of people.
