A+B=76
A-B=38

A=38+B

Substitute into other
38+B+B=76
2b=38
b=19
A+19=76
A=38
B=19

$A+B=76\\
A-B=38\ \ --->\ \ A=38+B\\\\
38+B+B=76\\
38+2B=76\ \ | subtract\ 38\\2B=38\ \ \ | divide\ by\ 2\\
B=19\\A=57\\\\
\frac{A}{B}=\frac{57}{19}=3$

Schach [20]

Answer:

The solutions are 270° and 450°.

Step-by-step explanation:

Given:

$cos\frac{x}{2} =\frac{\sqrt{2} }{2}$ .

So, the second and third quadrant angle to be calculated.

$cos\frac{x}{2}=135$

$=x=270$ °.

And, $cos\frac{x}{2}=225$

$=x=450$ °

Therefore, the solutions are 270° and 450°.

Find the value of c that makes t^2 - 22t+ c a perfect square trinomial.

allochka39001 [22]

The expression is a perfect square trinomial if and only if c = 121.

<h3>How to get the value of c?</h3>

A perfect square trinomial is written as:

(a + b)^2 = a^2 + b^2 + 2ab

In this case, we have:

t^2 - 22t + c

We can rewrite this as:

t^2 - 2*11*t + c

Then we have:

a = t

b = -11

And we will have that:

c = b^2 = (-11)^2 = 121

Then we have:

t^2 - 2*11*t + 121

Which is a perfect square trinomial:

(t - 11)^2 = t^2 - 22t + 121
