There exists a similar question where m angle 2 is 9y + 4. If the angles are supplementary, the sum of their measures is 180 degrees. The equation that represents this situation is,
4y + 7 + 9y + 4 = 180
The value of y is equal to 13. The value of the measure of angle 2 is equal to 121 degrees.

Answer:
59.6 ft²
Step-by-step explanation:
The surface area of the pillow is the total area of the net.
The net is made up of 3 rectangles and 2 congruent triangles.
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
<u>Rectangle 1</u> (left)
area = 4 × 5 = 20 ft²
<u>Rectangle 2</u> (middle)
area = 4 × 5.4 = 21.6 ft²
<u>Rectangle 3</u> (right)
area = 2 × 4 = 8 ft²
<u>Triangle</u>
area = 1/2 × 5 × 2 = 5 ft²
(Be careful here, as it is easy to use the wrong length for the base of the triangle. The base and height of the triangle are perpendicular, so at right angles to each other. Therefore, the base is 5ft and the height is 2ft)
Total area = rectangle 1 + rectangle 2 + rectangle 3 + 2 × triangle
= 20 + 21.6 + 8 + (2 × 5)
= 49.6 + 10
= 59.6 ft²
Answer: 13.3
Step-by-step explanation:
.
50.5 and 53.5
104-3=101 divided by 2=50.5 50.5+3 equals 53.5. 50.5+53.5=104
