What is the value of x ? enter your answer in the box ?

The correct answer is x = 8

Step-by-step explanation:

Points to remember :-

Angle sum property

Sum of angles of any triangle is 180°

From the figure we can see an isosceles triangle ABC

AB = BC

<A = <C = 69°

To find the value of m<B

<B = 180  - (<A + <C)

  = 180 - (69 + 69)

 = 180 - 138 = 42°

To find the value of x

<B = 42

5x + 2 = 42

5x = 42 - 2 = 40

x = 40/5 = 8

Therefore x = 8

x = 8

Step-by-step explanation:

Given in the question an isosceles triangle, in which the side AB and BC are similar so,

69 = (9y - 3)

69 + 3 = 9y

72 = 9y

y = 72/9

y = 8

Now as we know that sum of triangle is 180°, we will add all 3 angles and equal them to 180°

69 +  (9(8) - 3) + 5x+2 = 180

69 + ((72 - 3) + (5x + 2) = 180

69 + 69 + 2 + 5x = 180

140 + 5x = 180

5x = 180 - 40

5x = 40

x =  40/5

x = 8

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
