Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral.
Nadusha1986 [10]

Here is a reference to the Inscribed Quadrilateral Conjecture it says that opposite angles of an inscribed quadrilateral are supplemental.

Explanation:

The conjecture, #angleA and angleC# allows us to write the following equation:

#angleA + angleC=180^@#

Substitute the equivalent expressions in terms of x:

#x+2+ x-2 = 180^@#

#2x = 180^@#

#x = 90^@#

From this we can compute the measures of all of the angles.

#angleA=92^@#

#angleB=100^@#

#angleC=88^@#

<span>#angleD= 80^@#</span>

Find the value of 3 4(16 - 9). 31 49 58
maw [93]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

3+4(16-9)

We first solve the brackets:

(16-9) = 7

Now, we multiply it with 4

7\times 4=28

Now, we add 3 to it:

28+3=31

Hence, the value of expression would be 31.

Therefore, First option is correct.
