The triangle sum theorem says all 3 interior angles must equal 180 degrees.
so, 43 + 35 = 78. [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.
102 + 18 = 120. [180 - 120 = 60}
leaving the measure of Angle A as 60 degrees.

Answer:11 is q2 12 is 3/4
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
We have to find same denominator for both fractions;
3/4= 9/12
1/3= 4/12
9/12 minus 4/12= 5/12
You will need 5/12 powder more for the experiment.
