The equation for finding the area of one triangle is A=1/2(B)(H)
because we have two triangles, we do not need to divide the answer by two.
That being said, 8 times 12 is 96.
By installing a sprinkler for every 10 sq ft. of land we divide that by 10 and get 9.6
Because the decimal value is above 5, my answer would be that you need 10 sprinklers.
Answer:
$12.50
Step-by-step explanation:
take $250 and divide by 20
Answer:
a) 150°
b) 30°
Step-by-step explanation:
It is easier to work the exterior angle first.
<h3>b)</h3>
The sum of exterior angles is 360°. The exterior angle at any vertex of a regular dodecagon will be 1/12 that:
360°/12 = 30° . . . the measure of one exterior angle
__
<h3>a)</h3>
The measure of an interior angle will be the supplement of the adjacent exterior angle.
180° -30° = 150° . . . the measure of one interior angle
24+24+11+11=60?
48+22=60?
60=60?
:D You're correct
