2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
Answer:
y=-1x+8
Step-by-step explanation:
idk what to do here
Answer:
x = -9
Step-by-step explanation:
ANGLES IN A TRIANGLE ADD UP TO 180°
50° + 80° = 130°
180° - 130° = 50
x+59 = 50
x = -9
Answer:
(5,4) and (3,4)
Step-by-step explanation:
A line segment has 2 end points which can be denoted as:
and 
When this line segment intersects at y.
This means that the coordinate on the y axis is the same at both end points
i.e.

and
becomes
and 
x1 and x2 can be any value but the y value must remain unchanged
Using the above analysis, a possible coordinate is:
and 
Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form
<em> and </em>
<em />
Take for instance, another possible pair is:
and 
Bianca is 4'12, cause brian is 4'6, brianna is 3 inches taller so thats 4'9, Bianca is 3 inches taller than Brianna so she is 4'12
Just add three each time, 6+3=9 9+3=12
