The answer is the SAS postulate. The two triangles have two pairs of corresponding, congruent sides, and the included angles are congruent. And thus, triangles XYZ and ABC are congruent by the SAS postulate.
Answer:
3.14 cm
Step-by-step explanation:
From the question,
Applying
s = πdФ/360................... Equation 1
Where s = length of arc AB, d = diameter of the circle, Ф = angle at the center of the circle, π = pie
From the question,
Given: d = 8 cm, Ф = π/4 rad = 45°
Constant: π = 22/7
Substitute these values into equation 1
s = (22/7)(8)(45)/360
s = 3.14 cm.
Hence the lenght of arc AB = 3.14 cm
A the other ones really don’t make sense
Answer: 5
Step-by-step explanation: 4 + 3 + -2 = 5
Answer:
r = 13, 3
Step-by-step explanation:
| r - 8| = 5
All solutions for r by breaking the absolute value into the positive and negative components
r = 13, 3
