1. The measures of the angles of a triangle are in the extended ratio 3:5:7. What is the measure of

slega [8]

Answer:

b) 36

Step-by-step explanation:

ratio of angles = 3:5:7

The angles are 3x, 5x , 7x

Sum of all the three angles of triangle = 180

3x + 5x + 7x = 180

15x = 180

x = 180/15

x = 12

Shtirlitz [24]

Answer:

$area = 2.54 {ft}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$area \: of \: circle \: = \pi {r}^{2}$
