ABCD is a parallelogram. What is the measure of ∠ACD?

Igoryamba

Step-by-step explanation:

Here

5x+16+7x-3+6x+5 = 180(being sum of triangle)

or, 18x=180-18

or, x= 162/18

so, x = 9

now,

here,

<ACD = <ACB(diagonals of parallelogram bisect eachother)

or, <ACD = 7x-3

or, <ACD = 7×9-3

or, <ACD = 63-3

So, <ACD = 60°

On the grid draw the graph of x + 2y =7

Elena-2011 [213]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$x + 2y = 7$

Required

Draw the graph

First, we identify at least 2 possible values of x and y

Let $x = 1$

Solve for y

$x + 2y = 7$

$1 + 2y = 7$

$2y = 6$

$y = 3$

So, a point is: $(1,3)$

Let $x = 3$

Solve for y

$x + 2y = 7$

$3 + 2y = 7$

$2y = 7 -3$

$2y = 4$

$y = 2$

So, another point is: $(3,2)$

Plot $(1,3)$  and  $(3,2)$  on the graph, then draw a straight line through both points
