Question

Please help me on this!!

Answer 1

Hi there!

Let's solve this problem step by step!
The sum of the angles measures 360°, which is given in the question.

We can also express the sum of the angles as a sum of variables. To do this we must add all the variables a.
$a + a + 2a + 2a =$

Collect terms.
$6a$

When we have this expression and the sum of the angles, we can set up and solve an equation.
$6a = 360$

Divide both sides by 6.
$a = \frac{360}{6} = 60$

Therefore a = 60°
~ Hope this helps you!

Answer 2

Hi there!

∵ Sum of all th' Angles = 360°

Add th' angles :-

2a + a + 2a + a = 360°

=> 6a = 360°

=> a = $\dfrac {360}{6}$° = 60°

Hence,
The required angles are :-

• a = 60°
• 2a = 120°
