<2 + 95 = 180 straight line

<2 = 180-95 = 85

right angle +144 + <2 + <1 = 360 degrees ( quadrilateral)

substitute knowns

90 +144 +85 +<1 = 360

combine like terms

319 +<1 =360

<1 =41

0.6 * 100%

= 60%

I) Solve the equation sin2x + 3cos2x = 0 (for 0 till 360°)

galina1969 [7]

Get rid of cos2x by dividing both the values. So Sin2x/cos2x +3cos2x/cos2x.
Tan2x = 3
2x = -71.5 so x is -35.6
Use the quadrant method and add 360 twho the two values tou get.

The elevation E, in meters, above sea level at which the boiling point of a certain liquid is t degrees Celsius is given by the

otez555 [7]

Given function is

$E(t) = 1100(80 - t) + 500(80 - t)^2$

At t= 79.5 degree.

So we can place t= 79.5 in given equation

$E(79.5) = 1100 (80 - 79.5) + 500* (80 - 79.5)^2
$
= $1100 * 0.5 + 500 * (0.5)^2$
= $550 + 500 * 0.25$
= $550 + 125 = 625$

So elevation equal to 625 meter at t = 79.5 degree.
