It's 60 degrees you're welcome

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.

How do i write improper fractions as mixed numbers?<br> Explain with examples
Lynna [10]

Answer:

You have to multiply the whole number by the denominator and then add the answer you get with the numerator.

Step-by-step explanation:

For example, the fraction 10 \frac{3}{5}  is a mixed number, right? So then you multiply 10x3=30. Then you add 30+5=35. So then the answer would be \frac{35}{5}.

Hope this helps! Please give brainlist!
