A cyclic quadrilateral is a quadrilateral inscribed in a circle

The measure of angle A is 106

<h3>How to determine the measure of angle A</h3>

From the question, we have:

<C= 74

Opposite angles of a cyclic quadrilateral add up to 180.

So, we have:

<A + <C = 180

This gives

<A + 74 =180

Subtract 74 from both sides

<A =106

Hence, the measure of angle A is 106

Explain how you use a net to find the surface area of a prism.

patriot [66]

Step-by-step explanation:

To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.

Hope this helps!

All the love, Ya boi Fraser :)

Answer:

First option is the right choice.

Step-by-step explanation:

$\frac{1}{\cos \left(x\right)+1}+\frac{1}{\cos \left(x\right)-1}\\\\\frac{\cos \left(x\right)-1}{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}+\frac{\cos \left(x\right)+1}{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}\\\\=\frac{\cos \left(x\right)-1+\cos \left(x\right)+1}{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}\\\\=\frac{2cos\left(x\right)}{cos^2\left(x\right)-1}\\\\=\frac{2cos\left(x\right)}{sin^2\left(x\right)}$

$=2\cdot \frac{cos\left(x\right)}{sin\left(x\right)}\cdot \frac{1}{sin\left(x\right)}\\\\=-2cot(x)csc(x)$

There is 2 and 3/4 punds of roast beef and 1 and 7/8 pounds of turkey and 2 1/16 pounds of salami if you must put 1/4 of pound o

rosijanka [135]

2 and 3/4 punds of roast beef 2 3/4 = (4x2) + 3 /4= 11/4 roast beef

1 and 7/8 pounds of turkey 1 7/8 = 15/8 turkey

2 1/16 pounds of salami 2 1/16 33/16 salami

if you put 1/4 of pound of meat
then 11/4 roast beef divided by 1/4 = 11/4 x4 = 11 sandwiches roast beef

15/8 turkey divided 1/4 = 15/8 x 4 = 15/2 = 7 sandwishes

33/16 salami divided 1/4 = 33/16 x 4 = 33/ 4 = 8 sandwiches
