Answer:
AC=42
EB=21
BC=26
thats all i know, sorry hope u figure it out
Step-by-step explanation:
The sides are AC = 42, EB = 21, BC = 26, AB = 38 and the measures of angles are ∠ADC = 90°, ∠ABD = 38°, ∠BCA = 52°, ∠DEC = 104°.
What is Rectangle?Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles
Given is a rectangle ABCD.
AC and BD are diagonals intersecting at E.
Given DB=42, AD=26 and m ∠DAE=52°
(a) Diagonals of a rectangle are of equal length.
AC = DB = 42
(b) Diagonals of a rectangle bisect each other.
DE = EB = DB / 2 = 42/2 = 21
(c) Opposite side are equal.
BC = AD = 26
(d) Using Pythagoras theorem,
AB = [tex]\sqrt{(AC)^2-(BC)^2}[/tex] = [tex]\sqrt{42^2-26^2}[/tex] = 37.947 ≈ 38
(e) Measure of all the interior angles in a rectangle is 90°.
So, ∠ADC = 90°
(f) Given ∠DAE = 52°
∠BAE = 90° - 52° = 38°
ΔBAE is an isosceles triangle, since the two sides which are the bisectors of the diagonals are equal.
So, ∠ABD = ∠BAE = 38°
(g) ∠BCA = ∠DAE [Alternate interior angles]
∠BCA = 52°
(h) Sum of interior angles of a triangle is 180°.
∠DEC + ∠BDC + ∠ACD = 180°
∠BDC = ∠ABD = 38° and ∠ACD = ∠BAE = 38°
∠DEC = 180° - (38° + 38°)
= 104°
Hence the measures are found.

What is BC? Plz help
Answers
Answer and Step-by-step explanation:
To find the length of BC, we will be using the trigonometric function Sine.
The Sine trig function is as follows:
sin(θ) = [tex]\frac{Opposite Side}{Hypotenuse}[/tex]
Plug in the values and solve for the Hypotenuse (BC)
[tex]sin(45) = \frac{8}{x}[/tex]
Multiply x to both sides, then divide both sides by sin(45).
x = [tex]\frac{8}{sin(45)}[/tex]
Input into a calculator and solve.
The length of BC is [tex]8\sqrt{2}[/tex], or 11.3137.

b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3
