Answer:
x = 7
Step-by-step explanation:
Note that the line of length 2x - 6 is a mid- line segment as it bisects the 2 sides of the triangle. Accordingly it is half the length of the third side, that is
2x - 6 = 8 ( add 6 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
If I'm not mistaken, both should be the third option, or (C)
I can explain further in a reply, if needed.
37. complementary angles always add up to 90. just subtract 57 from 90 and you get 37.
Answer:
10x - 6y = 30
Step-by-step explanation:
Answer:
x∈[20/3;+∝).
Step-by-step explanation:
3x+10≥30; ⇔ 3x≥20; ⇔ x≥20/3
