Answer:

10

Step-by-step explanation:

Find the two similar sides which are already measured.

6 and 9 are those numbers.

Use similarity proportional ratio:

6/9 = z/15

Cross multiply:

9z = 15 × 6

9z = 90

z = 90 ÷ 9

z = 10

Answer:

SteAnswer:

y = 1/2x + 3/2

Step-by-step explanation:

Using the equation of the line

y - y_1 = m ( x - x_1)

First find the slope of the line

-2x + 4y = 8

It must be in this form

y = mx + C

4y = 8 + 2x

divide through by 4

4y/4 = 8 + 2x / 4

y = 8 + 2x/4

Let's separate

y = 8/4 + 2x/4

y = 2 + 1/2x

y = 1/2x + 2

Therefore, our slope or m is 1/2

Using the equation of the line

y - y_1 = m ( x - x_1)

With point (-5, -1)

x_1 = -5

y_1 = -1

y - (-1) = 1/2(x - (-5)

y + 1 = 1/2( x + 5)

Opening the brackets

y + 1 = x + 5 / 2

y = x + 5/2 - 1

Lcm is 2

y = x + 5 / 2 - 1/1

y = x + 5 -2/2

y = x +3/2

We can still separate it

y = x /2 + 3/2

y = 1/2x + 3/2

The equation of the line is

y = 1/2x + 3/2

The correct answer is A

2.   Using the external angle of a triangle theorem.

6x - 17 = 3x - 11 + 2x + 11

6x - 5x = 17

x  = 17

So  m angle K =  2(17) + 11

= 45 degrees   answer

3.  The diagonals are both medians of the triangle so the 2 parts are in the ratio  2:1  so  3:x = 2:1   and   x = 1.5  answer

2:1
