Answer:
9
Step-by-step explanation:
the triangle is right angle.
at right angle it makes 90°. therefore;
(3d+1)°+(6d+8)°=90°
3d+1°+6d+8°=90°
9d+9°=90°.
9d=90°-9°
9d=81°
d=81/9
d=9°
Answer:
x=0 and y=−2
keep scrolling it is kind of long
Step-by-step explanation:
−2x+2y=−4,3x−2y=4
−2x+2y=−4for x:
−2x+2y=−4
−2x+2y+−2y=−4+−2y
−2x=−2y−4
-2x/-2=-2y-4/-2
x=y+2
Substitute y +2 for x in3x−2y=4:
3x−2y=4
3(y+2)−2y=4
y+6=4
y+6+−6=4+−6
y=−2
Substitute −2 for y in x=y+2:
x=y+2
x=−2+2
x=0
x=0 and y=−2
