a straight line is 180 degrees

so on one side of A you have 98 so 180 - 98 = 82

82 + 32 = 114

180-114 = x = 66 degrees

Solve the equation for y. Then find the value of y for each value of x.<br><br> y+5x=9;x= -2, 0, 4

qwelly [4]

When x = -2

$y+5\left(-2\right)=9$

$y-5\cdot \:2=9$

$y-10=9$

$y-10+10=9+10$

$y=19$

When x= 0

$y+5\left(0\right)=9$

$y+5\cdot \:0=9$

$y+0=9$

$y=9$

When x= 4

$y+5\left(4\right)=9$

$y+5\cdot \:4=9$

$y+20=9$

$y+20-20=9-20$

$y=-11$

Plz help really bad at geometry

trapecia [35]

ST is a midsegment, which tells you that BD=2(ST) or ST=½BD. Use that to substitute the values and find ST.
BD=2(ST)
29+x=2(2x+31)
29+x=4x+62
29=3x+62
-33=3x
x=-11
Now that we know x, we can substitute that into 2x+31 to find ST
ST=2x+31
ST=2(-11)+31
ST=-22+31
ST=9
