Mathematics
1 answer:
Radda [10]3 years ago
3 0

Answer:

35°

Step-by-step explanation:

Complementary angles has a sum of 90°

m<A + m<B = 90°

2x + 23 + 4x -29 = 90° add like terms

6x - 6 = 90° add 6 to both sides

6x = 96 divide both sides by 6

x = 16 now replace the x in m<B = 4x - 29 with 16

4×16 - 29 = 35

Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2 feet. What is the total length
juin [17]

Answer:

110 feet

Step-by-step explanation:

Given that,

Length of the rectangular garden = 9 1/4 feet = 37/4 feet

Width of the rectangular garden = 4 1/2 feet = 9/4 feet

We need to find the total length of fencing Mark needs to surround all 4 gardens.

The length for 1 garden = perimeter of the garden

The length for 4 garden = 4×perimeter of the garden

= 4×2(l+b)

=8(l+b)\\\\=8(\dfrac{37}{4}+\dfrac{9}{2})\\\\=8\times 13.75\\\\=110\ \text{feet}

Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
