Question

Angle a and angle b are linear pair of angles. If 4angle a=5angle b then find angle a and angle b

Answer 1

4a = 5b

a:b = 5:4

A/Q, 5 x + 4 x = 180

⇒ 9x = 180

∴ x = 20

·∴∠a=  100

∠b = 80

OK

Question;♡♡♡✧♥

Angle a and angle b are linear pair of angles. If 4angle a=5angle b then find angle a and angle b.

Given;༶•┈┈⛧┈♛♛•༶♥

• ≤A and ≤B are linear pair of angles.
• 4≤A = 5≤B

To find; .・゜゜・♥　

Angle A(≤A) and Angle B(≤B).

Solution;♛⛧•༶♥　

• 4≤A = 5≤B

≤A = 5≤B/4

So,▧▧♡♡♡　　

• ≤A + ≤B = 180°

5≤B/4 + ≤B = 180°

9≤B/4 = 180°

9≤B = 180×4

≤B = 720/9

≤B = 80°

Then,▥▥♡♡♡

≤A = 5≤B/4

≤A = (5×80)/4

≤A = 400/4

≤A = 100°

Now, ▤▤♡♡♡

• ≤A = 100°
• ≤B = 80°
• ≤C = ≤A = 100° [Internal vertically opposite angles]
• ≤B = ≤D = 80° [Internal vertically opposite angles]

We have found;░░░♥　　

• ≤A = 100°
• ≤A = 100° ≤B = 80°

Analysis;.・゜-: ✧ :-♥　　　

Angle a and b are linear pairs... and Angle A and B has given.

Process used to solve;⋇⋆✦⋆⋇♥　　

• The Sum of linear pairs angle is 180°

≤A + ≤B = 180°

• ≤ is denoted as Angle.
