If the angle G is moved to a different spot in the circle the angle FGH and angle FEH in the cyclic quadrilateral will change to make it supplementary.

<h3>How to find angles of cyclic quadrilateral?</h3>

A cyclic quadrilateral is inscribed in a circle. It has all its vertices on the circumference of the circle.

Opposite angles in a cyclic quadrilateral are supplementary angles. That means they add up to 180 degrees.

Therefore,

∠F + ∠H = 180°

∠G + ∠E = 180°

Hence, if we moved ∠G to a different spot on the circle, angle FGH would change but angle FEH will also change to make the two opposite angles supplementary.

Therefore, Felix was wrong.

Using PYTHAGORAS THEOREM answer the question A vertical pillar ab bent at c at a height of 2.4m and its upper end b touches the

Alisiya [41]

Answer:

5.4 m

Step-by-step explanation:

The Pythagorean theorem tells you the relationship between the various lengths is ...

cd² = ac² +ad²

cd² = (2.4 m)² + (1.8 m)² = 9.00 m²

cd = √(9.00 m²) = 3.0 m

Since cd = cb and ab = ac+cb, we have ...

ab = 2.4 m + 3.0 m = 5.4 m

IgorC [24]

The correct question is
<span>Yuri computes the mean and standard deviation for the sample data set 12, 14, 9, and 21. he finds the mean is 14. his steps for finding the standard deviation are below. what is the first error he made in computing the standard deviation
</span>see the picture in the attached figure N 1

we know that
The formula for Sample Standard Deviation is indicated in the attached figure N2

in this problem
n=4 and Yuri had to divide in the formula by 3

therefore
the answer is Yuri divided by n instead of n -1

15. During the summer, Briana runs an ice cream shop. Her biggest seller is waffle ice cream cones. She charges $1.85 for a waff

Ivahew [28]

15) It is given that the charge of the waffle cone = $1.85

Charge per scoop of an ice cream = $0.60

Let C be the total cost.

So, total charge of one wafflce cone ice cream = charge of the waffle cone + (0.6 times number of scoops

C = 1.85 + 0.6x

16) To find the cost for 6 scoops of ice cream, put x = 6 in the above expression and simplify.

C = 1.85 + 0.6(6)

= 1.85 + 3.6

= 5.45

Hence, cost of 6 scoops of ice cream = $5.45.
