We know that

[the length of a circumference]=2*pi*r
for r= 4 units
[the length of a circumference]=2*pi*4--------------> 25.12 units

if a  full circle (360°) has a length---------------------> 25.12 units
 arc for an angle of 72 °---------------------------> X
X=72*25.12/360------------> 5.024 units

the answer is 
<span>the length of the subtending arc for an angle of 72</span>° is 5.024 units

What is the equation of a line that has a slope of 4/5 and passes through the point (-2,4)?
SOVA2 [1]

Answer:

y = \frac{4}{5}x + 5\frac{3}{5}

Step-by-step explanation:

Let's do it in slope-intercept form, it will look like this:

m = slope

b = y -intercept

To find our equation we will plug in the slope, plug in the point given, and solve for b.

y = mx + b

y = \frac{4}{5}x + b

4 = \frac{4}{5}(-2) + b

4 = -\frac{8}{5} + b

5\frac{3}{5} = b

Plug the b into our original equation, and there is our answer!

y = \frac{4}{5}x + 5\frac{3}{5}

What two congruent triangles share the side AC?
forsale [732]

The two congruent triangles that share the side AC are (c) △ADC and △CFA

<h3>How to determine the congruent triangles?</h3>

For two triangles to share the sides AC, then the points A and C must appear on the names of the triangles

In option (c), we have A and C in the names of the triangles ADC and CFA

Hence, the two congruent triangles that share the side AC are (c) △ADC and △CFA
