Step-by-step explanation:

90+54+(5x+6)=180...(sum of angles of a triangle)

144+5x+6=180

5x=180-150
5x/5=30/5
x=6

54+90+6=150

150+5×=360

5×=360-150

5×=210

Solve for x.<br><br> X = ____?

I am Lyosha [343]

Set up a proportion
EA / EB = ED/ EC
16 / (5x + 2 + 16) = 12 / (12 + 24)
16/(5x + 18) = 12 / 36 Cross multiply
16 * 36 = (4x + 18)*12 Remove the brackets
576 = 48x + 216 Subtract 216 from both sides.
360 = 48x Divide by 48
360/48 = x
7.5 = x

What is the slope of the line through the points (-3, 5) and (4, 5)?

Natasha_Volkova [10]

Answer:

Slope: 0

Step-by-step explanation:

(-3,5) (4,5)

y2-y1/x2-x1

5-5/4+3=0/7

0/7 simplifies to 0.

So the slope of the line (-3,5) (4,5) is 0.

Hope this helps! ;)
