Answer:
As they triangles are congruent, we can say that, angle A = angle O
So, angle A = 105+25 =130
A = 180 - 130 = 50° all angles in a triangle add up to 180)
Soo 50° is the answer,
I'm not too sure about it but I think this is correct, hope this helps, correct me if I'm wrong....
Group1 Group2 Total
Category 1 30 90 120
Category 2 14 32 46
Total 44 122 166
Relative frequency:
Group 1 Group 2 Row Total
Category 1: 30/166 = 0.18 90/166 = 0.54 120/166 = 0.72
Category 2: 14/166 = 0.08 32/166 = 0.20 46/166 = 0.28
Column Total: 44/166 = 0.26 122/166 = 0.74 166/166 = 1.00
The relative frequency is the derived by dividing the amount per cell by the total balance, which is 166. It denotes the parts of the rows and columns against the whole table.
angle of triangle is 180°
the angle beside 70° is 70°also because it has mention it is an isosceles triangle so that the two angle must be same
third angle will be 180°-70°-70°=40°
You must add all sides together to get the perimeter.
The perimeter is 24
