WebFind the missing angle marked x. [2 marks] This is a 4 -sided shape, to work out the interior angles we calculate the following: (\textcolor {red} {n}-2)\times 180 =360\degree. Next we can work out the size of \angle CDB as angles on a straight line add up to 180\degree. 180 - 121 = 59\degree. Now we know the other 3 interior angles, we get that. Web13. jún 2024 · Angles in pentagons always add up to 540°. To find a missing angle in a pentagon, add up the 4 known angles and subtract this from 540°. We first add the 4 known angles: 120° + 100 + 100 + 110° = 430°. We then subtract this from 540°: 540 – 430 = 110 … The area of a rectangle is length × width, which can also be written as base × … Angle ‘b’ is 80° because all angles in a triangle add up to 180°.
