Remark

A cyclic quadrilateral is one whose vertices touch the circumference of a circle. It has the strange property that opposite angles add up to 180 degrees. "b" is opposite a 110o angle. Therefore b = 180 - 110 = 70 degrees.

Answer B

Hi!

So because the quadilateral is inscribed in a circle then opposing angles of that quadilateral are supplementary (that means they add up to 180°).

Since the angle opposite to b is 110°, then the measure of b is 70°.

b + 110° = 180°
b = 70°

The answer is B.

The length of two sides of triangle are 4cm and 5cm. Between what two
Elanso [62]

Answer:

1 and 9

Step-by-step explanation:

By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.

In other words, in a triangle with side lengths a, b, and c, we always have a+b > c.

Applying this to this question, the other side length, x, must satisfy the following inequalities:

4+5 > x,\\x+5 > 4,\\x+4 > 5.

Solving these inequalities gives

x < 9,\\x > -1,\\x > 1.

Combining these solutions, we have 1 < x < 9. Therefore, the length of the third side falls between 1 and 9.

find three consecutive odd integers such that the sum of the first and the third equals the sum of the second and 13
andreyandreev [35.5K]

Answer: The three odd integers are 11, 13 and 15.

Step-by-step explanation: The first point to note is that the three unknown numbers are consecutive, which means they follow one after the other. Also we are told that the numbers are consecutive “odd integers.” This also means there is a two-digit interval between one number and the next. Hence, if the first number is A, the next number will be A + 2, and the third number will be A + 2 + 2 (that is, A + 4)

At this point we can now derive the following expressions based on the information we have been given, which is;

The sum of the first and third (A + {A + 4} )equals the sum of the second and 13 ({A + 2} + 13). Therefore we can write this out as follows;

A + {A + 4} = {A + 2} + 13

After removing brackets we now have

A + A + 4 = A + 2 + 13

2A + 4 = A + 15

By collecting like terms we now have

2A - A = 15 - 4

(Remember that when a positive value crosses to the other side of the equation it becomes negative, and vice versa)

2A - A = 15 - 4

A = 11

Hence, the three consecutive integers are 11, 13 and 15.
