The answer would be 12 and is a constant
Answer:
<h2>
50°</h2>
Step-by-step explanation:
AB = AC
So, it is a isosceles triangle.
<B = <C = 65°
Sum of angles of triangle = 180°
< A + < B + <C = 180°
plug the values:
X + 65° + 65° = 180°
Calculate the sum
X + 130° = 180°
Move constant to R.H.S and change its sign
x = 180° - 130°
Calculate the difference
X = 50°
Hope this helps...
Good luck on your assignment...
You would have to do this (1.25X3)+(0.45X2)=x then x=4.65, because 3X1.25=3.75 and 2X0.45=90 and 3.75+90=4.65
Answer:
b) AC
Step-by-step explanation:
Exterior angle C is the sum of interior angles A and B. If angle A is 70, then angle B is 120-70 = 50. Angle C is the supplement of its exterior angle, so is 180-120 = 60.
The smallest angle is B, so the opposite side, AC, is the shortest side.
