Tap on the photo

first prove triangle BHC similar to FDC.Reason(AA)

then,provrSBH and GBH congruent(SAS)

CB=CG

CBG is an isolesis triangle

angle G and CBG is X

angle BCG=180-90-12=180-78=102

X=(108-102)/2=39

Answer:39°

Step-by-step explanation:

If you know some properties of circle you may solve it like this:

Since ∠CDF = 90°, FC is the diameter of the circle passing through C, D and F.

So B is the centre of the circle mentioned above as B is the mid-point of FC.

Then we have BF = BC = BD since they are all radii of the same circle.

∠BDF = ∠BFD = 12°

∠BDA = 90° + 12° = 102°

∠BDA + ∠BAD + ∠ABD = 180°

102° + x + x = 180°

x = (180° - 102°)/2 = 39°

To issacchoy1234: Nvm if you don't understand, this will be taught in 2nd term of S4 ;)

Answer:

In this section, we discuss box-and-whisker plots and the five key values. The key values are called a five-number summary, which consists of the minimum, first quartile, the set is put into increasing order, divides the data into two equal parts. First, we put the values in the data set into increasing order: 3, 5, 7, 8, 12, 13, the middle score for a set of data that has been arranged in order from least to greatest. A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).

A tourist in France wants to visit 8 different cities. If the route is randomly selected, what is the probability that she will
Harlamova29_29 [7]

Answer:

Probability p( selecting 8 cities alphabetically) = 2.48×10^-5

Step-by-step explanation:

Number of possible ways of choosing 8 cities=Permutation P(n,k) = n!/(n-k)!

P(8,8)= 8!/(8-8)! = 8! = 40,320

Probability (selecting 8 cities alphabetically) = 1/40320 = 2.48×10^-5

Geometry Special Quadrilaterals show work please
Charra [1.4K]

Answer:

a = 16

w = 125

x = 120

y = 55

Step-by-step explanation:

<u>FINDING 'a'</u>

31 = a + 46 / 2

62 = a + 46

16 = a

<u>FINDING 'w'</u>

* This section looks Non-Isosceles trapezoid so I will be following the rule according it

w + 55 = 180

w = 125

<u>FINDING 'y'</u>

y = 55

- Because of corresponding angles

<u>FINDING 'x'</u>

* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.

x + 60 = 180

x = 120

Hope this helped ^^

(Please inform me of any mistakes or misunderstandings!)
