Answer:
140°
Step-by-step explanation:
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
The value of the smallest angle is given as:
= 3/8 of the 160 angle
=3/8 × 160°
= 60°
The sum of the total angle = 360°
Hence:
360° = 60° + 160° + a
a = 360° - (60° + 160°)
a = 360° - 220°
a = 140°
Therefore, a = 140°
(3t² +t -12t - 4)(t+2)=0
(3t³ - 5t² -26t -8) =0
t = -2
