Answer:

The correct answer is  Option C . d -5

Step-by-step explanation:

<u>Identity: </u>   (a + b)(a - b) = a² - b²it is given that,

it is given that,

(d - 5)(?) = d² - 25

LHS = (d - 5)(?)

RHS = d² - 25

we can compare this with the identity.

here, a = d and b = 5

therefore we can write and start with RHS

RHS =  d² - 25 = d² - 5²  = (d +5)<u>(d - 5) </u>= LHS

(d +5)<u>(d - 5)</u>  =    d² - 25

Therefore option C. (d- 5) is the correct answer.

Hello! can you please, help me by finding some missing angles.
yuradex [85]

Answer:

Going horizontally,

Q1 a) x = 133°

Q1 b) x = 59°

Q1 c) x = 189°

Q1 d) x = 32°

Q1 e) x = 72°

Q1 f) x = 36°

Q2 a) x = 53°

Q2 b) x = 94°

Q2 c) x = 10°

Workings out:

To work out the interior angles, you need to know that angles on a straight line add up to 180°. In addition, you also need to know that angles around a point add up to 360°. When you need to find a missing angle, if the angle is on a line or in a triangle, take whatever value/values the angle/angles you have are and take it away from 180°. If the angle is around a point, (or in a square, where all angles are the same anyway) add however many values you have for the angles then take that away from 360°. Hope this helps! :)
