because proportion is right vertical
Answer:
9°
Step-by-step explanation:
In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.
Sum of angles in a ∆ = 180°
80° + m/_2 + m/_2 = 180°
80° + (5x + 5) + (5x + 5) = 180°
10x + 90° = 180°
10x = 90°
x = 9°
Yes the answer is 24 cm2
because the width is 4 cm then 2 width = 2(4) = 8 cm
perimeter = 20 cm
20-8=12 cm
so 12 cm left is 2 length then the length is 12/2= 6;cm
that's why the area is 4*6= 24 cm2
