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°
THE answer is 4% because u divide
Answer: 2
When x=-9, y=2. So, f(-9)=2.
the answer is 1052
5*2367 /9=1915
2367 -1315= 1052
9/27 or 9 to 27
