Answer:
∠K = ∠M = 55°
Step-by-step explanation:
The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...
4x -1 = 2x +27
2x = 28 . . . . . . . . add 1-2x to both sides
x = 14
4x -1 = 4(14) -1 = 55
The measures of the angles are ...
∠K = ∠M = 55°
Answer:
2
Step-by-step explanation:
• + • = ••
1 + 1 = 2
Some metals melt at lower temps than others. Tin becomes liquid at 231.8˚C (447.8˚F); at the other end of the spectrum, tungsten has the highest melting point of any metal: 3,422˚C (6,192˚F). Somewhere in the middle is mercury, which stays in a liquid state until its temperature drops to -40.
Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.
B
B is correct.
C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o
D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.
