You can do Guess and Check(but the smart way). You first get 102 and 12. Then, you can minus 3 from each one of them, getting 99 and 9, also being 11 times the other, so then the answer would be 180 - 99 or 90 - 9, equaling 81
1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.
1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.
The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.
So angles in a triangle add up to 180
Angle B is 50 and angle E is 90
90+50=140
180-140=40°(angle A)
Now the other triangle
Angle C is 62 and angle E is 90
90+62=152
180-152=28
40-28=12
hope this helped but I can't help with the second one
