Use the rule of angle opposite, as 70° is opposite the 2x°
2x° = 70°
2x = 70
x = 70 ÷ 2
x = 35
Then, now stay well simples:
Use the rule of angle opposite as :
(3x + 5)° = (x + 3y)°
3.(35) + 5 = 35 + 3y
110 = 35 + 3y
110 - 35 = 3y
75 = 3y
3y = 75
y = 75 ÷ 3
y = 25
If you want to check the answer, to see if it is correct. The sum of the four angles must be 360 °
As y = 25 and x = 35
(x + 3y)° = 35 + 3 . 25
= 110°
Then,
The sum of the 4 angles will be:
360° = 2 × 110° + 2 × 70°
360° = 220° + 140°
360° = 360°
Ohhh, that's right!
This the answer to the your question.
x = 35
And
y = 25
