Answer:

135°

Step-by-step explanation:

That triangle in the corner is an right angle isosceles triangle as that line the midpoint of both sides :

the base angle of this triangle (x) will be :

180 = 90 + 2x

90 = 2x

x= 45

Angles on a straight line add up to 180. So to work out a :

180 = 45 + a

135 = a

Mercedes takes out a loan for

vivado [14]

Answer:

Monthly payment = $50

Step-by-step explanation:

Principal, P = $15000

Rate , R = 4%

T= 48 months = 4years

$Interest = \frac{PRT}{100}$

$= \frac{15000 \times 4 \times 4}{100}$

$= 2400$

So, total interest for 4years ( or 48 months) is $2400

Therefore, monthly payment is

$=\frac{2400}{48} = \$ 50$

2 squares area is 125 yards and 5 yards. how many yards would it take to fence the two squares in separately

lesya692 [45]

Answer:

$24\sqrt{5}\ yards$

Step-by-step explanation:

Let A1 be the area of one square and A2 be the area of second square

So,

A1 = s^2

where s is side of square

$s^2=125\\\sqrt{s^2}=\sqrt{125}\\s=\sqrt{25*5}\\ s= \sqrt{5^2 * 5}\\ s= 5\sqrt{5}$

So side of one square is $5\sqrt{5}$

To calculate the length of fence we need to find the perimeter of the square

So,

P1 = 4 * s

$=4*5\sqrt{5} \\=20\sqrt{5}$

For second square:

$A_2=s^2\\5=s^2\\\sqrt{s^2}=5\\{s}=\sqrt{5}$

The perimeter will be:

$P_2 = 4*s\\=4 * \sqrt{5} \\=4\sqrt{5}$

So the total fence will be: P1+P2

$= 20\sqrt{5}+4\sqrt{5} \\= 24\sqrt{5}\ yards$
