ok so since the total measurement is 180° and you know that 1 of the sides is 40° and the other 2 are the same you will just need to subtract 40 from 180 and split that in half
here's the formula
therefore
x=70°

Answer: p = 100
20/p = 2/10; Cross Multiply
(p * 2) = (20 * 10)
2p = 200; divide 2 from both side
p = 100
Check:
Put 100 in for p
20 / 100 = 2 / 10; is true so 100 is correct
Answer:
a = 1 b = -1.
Step-by-step explanation:
Suppose the quotient when you divide x^4+x^3+ax+b by x^2 + 1 is
x^2 + ax + b then expanding we have:
(x^2 + 1)(x^2 + ax + b)
= x^4 + ax^3 + bx^2 + x^2 + ax + b
= x^4 + ax^3 + (b + 1)x^2 + ax + b Comparing this with the original expression:
x^4 + x^3 + 0 x^2 + ax + b Comparing coefficients:
a = 1 and b+ 1 = 0 so b = -1.
