Okay so a right angle is 90 degrees so we take 90 degrees and subtract 63 from it
90-63=17 degrees
so X=17
Then in order to find Y, we have to realize these are alternate interior angles so they equal the same
your equation is 3y=63
you divide y by 3 to isolate it and
Y= 21
Hope this helps:)
Answer:
a₂ = - 28.5
Step-by-step explanation:
the nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 45 and given a₃ = - 12 , then
a₁ + 2d = - 12 , that is
- 45 + 2d = - 12 ( add 45 to both sides )
2d = 33 ( divide both sides by 2 )
d = 16.5
Then
a₂ = a₁ + d = - 45 + 16.5 = - 28.5
Obtuse isosceles
it has 2 congruent sizes, no right angles and seems two big to be acute
Plug in 5 for x into the u function.
U(5) = 4(5)+5 = 25
That means w(u(5)) = w(25) = -25 + 1 = -24
Answer: 7.5 minutes (7 min 30 sec)
Step-by-step explanation: If it takes it 3 minutes to travel 2 km, it would take it 1.5 minutes to travel 1 km. So, 1.5 * 5 = 7.5, meaning it would take it 7.5 min to travel 5 km.
