Answer:
x + 100+ 3x = 180
4x + 100 = 180
4x = 180-100
<u>4</u><u>x</u><u> </u> = <u>8</u><u>0</u>
4. 4
x= 20°
Answer: The required polynomial of lowest degree is 
Step-by-step explanation: We are given to find a polynomial function of lowest degree with real coefficients having zeroes of 2 and -5i.
We know that
if x = a is a zero of a real polynomial function p(x), then (x - a) is a factor of the polynomial p(x).
So, according to the given information, (x - 2) and ( x + 5i) are the factors of the given polynomial.
Also, we know that complex zeroes occur in conjugate pairs, so 5i will also be a zero of the given polynomial.
This implies that (x - 5i) is also a factor of the given polynomial.
Therefore, the polynomial of lowest degree (three) with real coefficients having zeroes of 2 and -5i is given by

Thus, the required polynomial of lowest degree is

Answer:
1/5 is left.
Step-by-step explanation:
Portion remaining after the bar was eaten by his brother = 1 - 1/5 = 4/5.
Portion remaining after John ate 3/4 of this = 4/5 - 3/4* 4/5 = 4/5 - 3/5
= 1/5.
