Answer:

4 a + 2b = 360 ----->equation 1

a + b = 116 --------> equation 2

a = 64 °

b = 52°

Step-by-step explanation:

The sum of all of the internal angles would be 360°.  Since we have four "a"s and two "b"s, we have:

4a + 2b = 360

Then told that the largest internal angle of the parallelogram is 116 degrees, so:

a + b = 116

We now have a system of two equations and two unknowns.

I'll simplify the first equation by dividing both sides by 2, then multiplying the second equation by -1 to prepare for solving by elimination:

2a + b = 180

-a - b = -116

----------------------  Add the equations together to get:

a = 64°

Now we can solve for b:

a + b = 116

64 + b = 116

b = 52°

So the values of "a" and "b" are:

a = 64° and b = 52°

Hope this helped :)

A pizza has a 14-inch diameter. What is the approximate area of the pizza? USE 3.14 for π.
REY [17]

Answer:

Step-by-step explanation:

How approximate is approximate?

I'll give you an answer to 2 decimal places.

Area = pi * r^2

r = d/2

d = 14

r = 14/2

r = 7

Area = 3.14 * 7^2

Area = 3.14 * 49

Area = 153.86 sq in.

Lots of pizza! Enjoy!
