Answer:
The answer is 7/20
Step-by-step explanation:
I think the answer is either b or c i am not sure
Given that,
The area parameters are
A = 2.7 cm, B = 4.1 cm C = 4.5 cm
We want to find the angle extended by B.
Using cosine Rule
b² = a² + c² - 2ac•Cosθ
4.1² = 2.7² + 4.5² - 2 × 2.7 × 4.5• Cosθ
16.81 = 7.29 + 20.25 - 24.3•Cosθ
16.81 - 7.29 - 20.25 = -24.3•Cosθ
-10.73 = -24.3•Cosθ
Cosθ = -10.73 / -24.3
Cosθ = 0.4416
θ = Cos~1 (0.4416)
θ = 63.8°
The angle B is 63.8°
what is the equation in slope- intercept form of the line that passes through the points (-26 -11) and (39, 34) ?
A) y = -9/13 x + 7
B) y = -9/13 x - 7
C) y = 9/13 x + 7
D) y = 9/13 x - 7
step 1
Find out the slope
m=(34+11)/(39+26)
m=45/65
simplify
m=9/13
step 2
Find the equation in slope intercept form
y=mx+b
we have
m=9/13
point (39,34)
substitute and solve for b
34=(9/13)(39)+b
b=34-27
b=7
therefore
the equation is
y=(9/13)x+7
<h2>option C</h2>
