Use rectangle ABCD and the given information to solve each problem.
solong [7]

Problem 1

<h3>Answers:</h3><h3>angle 6 = 50</h3><h3>angle 7 = 50</h3><h3>angle 8 = 40</h3>

--------------------

Work Shown:

point E = intersection point of diagonals.

x = measure of angle 6

y = measure of angle 8

angle 7 is also x because triangle AED is isosceles (AE = ED)

Focus on triangle AED, the three angles A, E, D add to 180

A+E+D = 180

x+80+x = 180

2x+80 = 180

2x = 180-80

2x = 100

x = 100/2

x = 50

So both angles 6 and 7 are 50 degrees.

Turn to angle 8. This is adjacent to angle 7. The two angles form a 90 degree angle at point A. This is because a rectangle has 4 right angles.

(angle7)+(angle8) = 90

50+y = 90

y = 90-50

y = 40

angle 8 = 40 degrees

=================================================

Problem 2

<h3>Answers:</h3><h3>angle 2 = 61</h3><h3>angle 3 = 61</h3>

--------------------

Work Shown:

Angle 5 is 29 degrees (given). So is angle 4 because these are the base angles of isosceles triangle DEC (segment DE = segment EC)

angle 3 and angle 4 form a 90 degree angle

x = measure of angle 3

(angle 3)+(angle 4) = 90

x+29 = 90

x = 90-29

x = 61

Angle 2 is congruent to angle 3 since triangle BEC is isosceles (BE = EC), so both angle 2 and angle 3 are 61 degrees each.

Answer:

Step-by-step explanation:

In my opinion, I beleive it's y=9 becasue the rest of the equations have x in them. bth, this is me just by looking at the equation.

Minchanka [31]

Remember that the y-intercept is where the function has a value of x = 0 and the x-intercept is where the function has a value of y = 0. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.


<u>x-intercept</u>

Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for x.

0 = -2x - 3

  • Set up

3 = -2x

  • Add 3 to both sides

x = - \dfrac{3}{2}

  • Divide both sides by -2

The x-value of the x-intercept is -\frac{3}{2} and the y-value is 0, meaning that the x-intercept has coordinates \boxed{(-\frac{3}{2}, 0)}.


<u>y-intercept</u>

Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for y:

y = -2(0) - 3

  • Set up

y = -3

  • Multiply and simplify

The y-value of the y-intercept is -3, meaning that the y-intercept of the function is \boxed{(0, -3)}.
