Answer: -0.75 sorry if wrong please don’t report me thank you
Step-by-step explanation:
the slope formula is y2 - y1/ x2 - x1
*substitute values*
3 - 9/ 5 - -3
*change double negative to positive*
3 - 9 / 5 + 3
*solve*
-6 / 8
*divide*
-0.75
-0.75 is your answer
we could look at the picture with a bit less lines, check the picture below.
that simply means that those two blue angles are linear angles and therefore add up to 180°.

Answer:
<em>x = 7.5 cm </em>
Step-by-step explanation:
ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.
= 
AC = 4 + 6 = 10 cm
= 
⇔ 10x = 6(x + 5) ⇒ <em>x = 7.5 cm</em>
Answer:
Step-by-step explanation:
m∠EBC = 45°
3x + 9y = 45
Divide the entire equation by 3
x + 3y = 15 --------------------(I)
m∠EAB = 45
5x + 5y = 45
Divide the entire equation by 5
x +y = 9 -------------(II)
Multiply equation (II) by (-1)
(I) x + 3y = 15
(II)*(-1) <u> - x - y = -9</u> {Now add}
2y = 6
y = 6/2
y = 3
Plugin y = 3 in equation (I)
x + 3*3 = 15
x + 9 = 15
x = 15 - 9
x = 6
