Answer 1

$\bf \huge {\underline {\underline \red{AnSwEr}}}$

⠀⠀⠀⠀⠀⠀

Given

⠀⠀⠀

• AB || HF

⠀⠀⠀

• DE || FG

⠀⠀⠀

• ∠HFC = 30°

⠀⠀⠀

• ∠EDB = 60°

⠀⠀⠀

To Find

⠀⠀⠀

• ∠FDE

⠀⠀⠀

Solution

⠀⠀⠀

∠HFC = ∠ADF = 30° [ Corresponding Angle ]

⠀⠀⠀

➨∠ADF + ∠FDE + ∠EDB = 180° [ Straight angle ]

⠀⠀⠀

➨ 30° + ∠FDE + 60° = 180°

⠀⠀⠀

➨ ∠FDE + 90° = 180°

⠀⠀⠀

➨ ∠FDE = 180° - 90°

⠀⠀⠀

➨ ∠FDE = 90°

⠀⠀⠀

Therefore, ∠FDE = 90°

Answer 2

Answer:

Angle CFA and angle FDA are alternate angles so,

angle CFA = 30°...........( Given)

therefore angle CFA = angle FDA.....( alternate angles)

therefore,

angle FDA = 30°

Now,

On the straight line there is point D which is equal to 180° means Supplementary angle. But we can see here that there are 3 angles, by calculating it we can find the angle FDE, let's start,

let the angle FDE be x

angle FDA + angle FDE + angle EDB = 180°

30° + x° + 60° = 180°

x+ 90° = 180°

x= 180° – 90°

x = 90°

therefore,

angle FDE = x = 90°

Hope this will help!!! you
