Use pythagorean theorum: c^2 = a^2 + b^2, where BC = c, AB = a, AC = b so b^2 = c^2 - a^2 --> b = SR(c^2 - a^2), where SR means square root of ( ) b = SR(64 - 49) = SR(15) = 3.873 = B) 3.87 units
What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
The measures of the angles in △abc are given by the expressions in the table. angle measure angle a 65° angle b (3x−10)° angle c (2x)∘ find the value of x. then find the m∠b and m∠c.
