The measure of its supplementary angle is 42 degrees
The sum of supplementary angle is qual to 180 degrees
Let the required angle be x
The sum of the supplements of 138 degrees will be expressed as:
x + 138 = 180
x= 180 - 138
x = 42 degrees
Hence the measure of its supplementary angle is 42 degrees

Answer:
The side opposite the right angle is the hypotenuse. The Pythagorean theorem is used to solve for the length of the hypotenuse. If a right triangle has legs measuring a and b with hypotenuse c, the Pythagorean theorem is a² + b² = c². Solving for c is as simple as taking the square root of both sides of the equation.
A would be the correct answer:) hope this helps!!
Answer:
12
Step-by-step explanation:
Since we know that 9 is 3/4 of what she needs you would divide 9 by 3 so we know how much 1/4 of a cup is worth.
(9/3=3) now we know she needs 3 cups of flour for 1/4 of the expression. Now we multiply 3 by 4 so we can get the answer.
(3x4=12)
Molly needs 12 cups of flour to make bread.
