Apply exponent rule, 
We have,
Cancel out common factor b,
We have
Thus, the given expression simplified to
Answer:
a = 60
b = 120
c = 120
Step-by-step explanation:
A has the same angle as 60 degrees
To find b
60 + b = 180
b = 120
C has the same angle as b
So c = 120
I know I'm bad at explaining.
Answer:
Because triangle has three sides
34+50+50+50-60+22
You add everything except 60 because deposits mean add money to the account. You subtract 60 because a withdrawal is taking money out of the account. There are three 50s because you deposit $50 each day for 3 days.
<u>We'll assume the quadratic equation has real coefficients</u>
Answer:
<em>The other solution is x=1-8</em><em>i</em><em>.</em>
Step-by-step explanation:
<u>The Complex Conjugate Root Theorem</u>
if P(x) is a polynomial in x with <em>real coefficients</em>, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).
The question does not specify if the quadratic equation has real coefficients, but we will assume that.
Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
