Answer:
1. T =34
2.143 =exterior A
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees
T+H+E =180
T + 107+39 = 180
Combine like terms
T +146 = 180
Subtract 146 from each side
T +146-146 = 180-146
T =34
The exterior angle is the sum of the opposite interior angles in a triangle.
B+T =exterior A
66 +77 = exterior A
143 =exterior A
Answer:
Step-by-step explanation:
From the picture attached,
Segment AB has been divided into four equal parts.
Let each part measures equal length = 1 unit
Point C is 2 units apart from both the points A and B.
Length of AC = Length of BC = 2 units
Therefore, point C will be the mid point of segment AB.
And ratio of AC and BC = 1:1
AC:BC = 1:1
Similarly, AC:AB = 2:4
= 1:2
And BC:AB = 2:4
= 1:2
Ur answer will be - A≈69.65cm².
