Answer:

143 degrees.

Step-by-step explanation:

m < A + m < B = 180 degrees. ( inside angles of a parallelogram). So:-

4x - 9 + x - 1 = 180

5x - 10 = 180

5x = 190

x = 38

So m < A = 4(38) - 9

= 143 degrees.

Answer:

Step-by-step explanation:

This is a Pythagorean Theorem Question

c^2 = a^2 + b^2

c= sqrt(5)

a = x

b = x This is an isosceles right triangle. The vertical side and the horizontal side are equal.

x^2 + x^2 = sqrt(5)^2

2x^2 = 5 Divide both sides by 2

x^2 = 5/2 Take the sqrt of both sides.

√x^2 = √5 / √2 Multiply right side by √2 on both top and bottom

x = √5*√2 / √2*√2

x = √10 /2

We can use a ratio to solve

12 hours x hours

---------- = ------------

93 dollars 62 dollars

Using cross products

12 * 62 = 93x

Divide each side by 93

12*62/93 = 93x/93

8 = x

Answer:

Therefore,

$C=\pi d\\C\approx 3.14 \times d\\C\approx 43.96\ inches$

Step-by-step explanation:

Let Assume Some Diameter of a Circle, to Solve it

Diameter = d = 14 inch ( say )

C =Circumference

Pi =constant = 3.14

To Find:

C = ?

Solution:

Formula for Circumference of a Circle is given as

$C=\pi d$

Where,

C = Circumference

d = Diameter

Now Substitute d = 14 inches we get

$C=3.14\times 14\approx 43.96\ inches$

This way we can find the circumference for any 'd' i.e Diameter

Therefore,

$C\approx 43.96\ inches$
