Answer:

53.14 units

Step-by-step explanation:

Length of arc is given as:

l =  \frac{ \theta}{360 \degree}  \times c \\  \\  \therefore \: 12.4 =  \frac{84 \degree}{360 \degree}  \times c \\  \\   \therefore \: 12.4 =  \frac{7}{30}  \times c \\  \\ \therefore \: c =  \frac{12.4 \times 30}{7}  =  \frac{372}{7}  = 53.1428571 \\  \\ \therefore \: c =53.14 \: units

Let's say we have a triangle with sides called a, b, and c, and that b is the base. Our triangle has a height that we'll call h.
Irina18 [472]

Answer:

16.34 square inches.

Step-by-step explanation:

Given:

Base of triangle, b = 3 inches

Height of triangle, h = 10.89 inches

Question asked:

What is the area of this triangle in square inches?

Round your answer to the nearest hundredths place .

Solution:

As we know,

Area\ of\ triangle =\frac{1}{2} \times base\times height

                           =\frac{1}{2} \times3\times10.89\\\\ =\frac{32.67}{2} \\\\ =16.335

As, we have to find the answer to the nearest hundredths place, hence the area of triangle will be 16.34 square inches.

The length of a rectangle is 6 inches less than twice its width, and the perimeter is 72. What
abruzzese [7]

Answer:

Length=22 inches and width=14 inches

Step-by-step explanation:

According to the 1st condition

Perimeter=72

or, 2(l+b)=72

or, l+b=36..................equation(i)

According to second condition

l=2b-6.........................equation(ii)

Substituting the value of l form equation (i) to equation(ii)

2b-6+b=36

b=14

l=2*14-6

=22
