200,000+ 70,000+ 7,000+ 100+ 80
Answer:
34 degrees and 131 degrees
Step-by-step explanation:
Complementary angles always add up to 90 degrees
90 - 56 = 34 degrees (1)
180 - 49 = 131 degrees (2)

x∈(-∞,3]
Answer:
The equation that can be used to find the width is 2(13 + w) = 42
The width of the rectangle is 8 inches
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width
∵ One rectangle has a length of 13 inches
∴ l = 13 inches
∵ Its perimeter is 42 inches
∴ P = 42 inches
- Substitute the values of l and P in the formula of the perimeter
∵ 42 = 2(13 + w)
The equation that can be used to find the width is 2(13 + w) = 42
To find W divide both sides by 2
∴ 21 = 13 + w
- Subtract 13 from both sides
∴ 8 = w
The width of the rectangle is 8 inches
The answer would be 7.99.
