Answer:

The formula to find the third side of the triangle is $a^2+b^2=c^2$

Step-by-step explanation:

In order to find value of the third side without knowing any degree measurements, you need to know value of two sides. Variable $c$ , in this case, is a hypotenuse (the longest side of the triangle).

In the accompanying diagram of rectangle ABCD, diagonal AC is drawn, DE = 8, DE 1 AC, and m2 DAC = 55. Find the area of rectangl

Aneli [31]

Answer:

sin (55) = DE / AD

AD = DE / sin (55)

AD = 8 / sin (55)

And

tan (55) = DC / AD

tan (55) = DC / [8 / sin (55) ]

DC = 8 tan (55) / sin (55)

AD * DC =

[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2

Graph the function y = 4 . Then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Elodia [21]

Given equation is y=4.

Question says to graph the given equation y=4 then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Equation y=4 has no "x" so that means line y=4 will be a horizontal line which passes through 4 on y-axis.

Since it is parallel to x-axis so that means there is no x-intercept.

y-intercept is (0,4) as the line crosses at 4 on y-axis.
