3 meters becasue in the span of 6 hours it went up 2 meters so basically it went up a meter every three hours so at t= 5 it would be three meters

Answer:

\frac{2  \: +  \: 3 \sqrt{5} }{3}

Step-by-step explanation:

\frac{2}{3}  +  \sqrt{5}  =

= \frac{2}{3}  + ( \sqrt{5}   \times  \frac{3}{3} )

= \frac{2}{3}  +  \frac{3 \sqrt{5} }{3}

=  \frac{2  \: +  \: 3 \sqrt{5} }{3}

SHORT RESPONSE Two angles of a triangle have measures of 35° and 80°. Find the values of the exterior angle measures of the tria
Oduvanchick [21]

Answer:

Step-by-step explanation:

Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.

35 + 80 + x = 180

115 + x = 180

x = 180 - 115

x = 65

Exterior angles are supplements of the interior angles.

So the exterior angle to 65 degrees is 180 - 65 = 115

And the exterior angle to 35 degrees is 180-35 = 145

The exterior angle to 80 degrees is 180 - 100 = 80

PLS HELP. I will give brainliest if you are correct!!!
pshichka [43]
We can see here that there are 2 triangular bases on the prism.

To calculate the area of a triangle, we multiply the base and the height and then divide by 2.

A = 8 x 6 /2

A = 48/2

A = 24

Hope it helps!
