Correct answer is c. Hope you have a good day
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
Y = mx + c
7= (-5)(-2)+ c
7= 10 +c
7-10=c
-3=c
Equation of the line: y = -5x-3
Sub in (a, 2)
2= - 5(a)-3
2+3= -5a
5= - 5a
1= - a
A = -1
This equation basically says that a number plus 3/5 equals 2 so we can simply:
2 - 3/5 = x
Therefore x equals 1 & 2/5 or 1.4
