Answer:
Both obtuse angles - 124°
Both acute angles - 56°
Step-by-step explanation:
The two given obtuse angles are equal. Therefore you get an equation
[tex]9y+7 = 2y+98\\7y=91\\y=13[/tex]
So the obtuse sizes of the two given angles are [tex]13*9+7=2*13+98=124[/tex]°
And the sizes of the acute angles are [tex]180-124=56[/tex]°
