This Question is actually for 44 points not 80 :(
Answer:
largest angle = 92°
Step-by-step explanation:
Since the measurement of the angles are;
x°, ( x + 6)°, (2x + 10)°
And we know that sum of angles in a triangle is 180. Thus;
x + (x + 6) + (2x + 10) = 180
x + x + 6 + 2x + 10 = 180
4x + 16 = 180
4x = 180 - 16
4x = 164
x = 164/4
x = 41°
The other two angles will be;
(41 + 6)° and (2(41) + 10)°
Which gives;
47° and 92°
So,largest angle = 92°
The answer is 150 parents. Because 450/3=150
180=2x+y
180-y=2x
(180-y)/2=x
(5-3)^2 is = -4 , the second one is -9.67
