Since the angle under angle 3 is a right angle (because of the little orange square) we can assume that angle 3 plus angle 2 equals 90 degrees. so
(2x - 5) + (4x - 13) = 90
6x - 18 = 90
6x = 108
x = 18
measure of angle 2 = 36 - 5 = 31
measure of angle 3 = 72-13 = 59
Answer:
the second one
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse
a² + b² = c²
in this problem, 4² + 10² ≠ 11²
16 + 100 ≠ 121
Answer:
DE = 4
Step-by-step explanation:
The bisector divides the triangle into proportional segments, so ...
FK/DF = EK/DE
5/10 = 2/DE . . . . substitute given values
DE = 4 . . . . . multiply by 2DE
