Triangle DEF contains right angle E. If angle D measures 50° and its opposite side measures 7.6 units, what is the measure of side DE? Round your answer to the nearest hundredth. 4.89 units 5.34 units 6.38 units 9.06 units

DE=6.38 units

Step-by-step explanation:

The triangle described in the problem is shown in the image below.

The opposite side of the angle of 50° is 7.6 units and we need to find the adjacent side of 50°.

The trigonometric ratio that relates both legs of a right triangle is the tangent. Its formula is as follows:

Solving for DE:

Operating and computing the tangent with a scientific calculator:

DE=6.38 units

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
