Answer:
Distance between the points (-3,1) and (1, -2),
Option C
Answer:
4.42
Step-by-step explanation:
Data obtained from the question include the following:
Angle θ = 70°
Hypothenus = AB = 13
Adjacent = BC =?
Sin 70° ≈ 0.94
Cos 70° ≈ 0.34
Tan 70° ≈ 2.75
Next, we shall determine the measurement of BC as follow:
Since we are to obtain the adjacent, we shall use the following equation:
Cos θ = Adjacent /Hypothenus
Cos 70° = BC /13
0.34 = BC /13
Cross multiply
BC = 0.34 x 13
BC = 4.42
Therefore, the measurement of BC is 4.42
Answer:
x = ±
Step-by-step explanation:
5x² - 3y = 4y + 8 ( add 3y to both sides )
5x² = 7y + 8 ( divide both sides by 5 )
x² = ( take square root of both sides )
x = ±
DE would be half of the length of AB
hope this helps
