An acute angle θ is in a right triangle with sin θ = seven eighths. What is the value of cot θ?

Draw a right triangle ABC, with m(CAB)=∅.

Let CB=7 units, AC=8 units, so by the Pythagorean theorem:

AB= \sqrt{ AC^{2} - BC^{2} }= \sqrt{ 8^{2} - 7^{2} }=  \sqrt{64-49} = \sqrt{15} (units)

so we have drawn a triangle where sin∅=7/8

in this triangle, cot∅=(adjacent side)/(opposite side)=\frac{ \sqrt{15} }{7}

Answer: <span>square root of fifteen divided by seven</span>

Given f(x)= 3x+21. A. F(4)=B. F(X)= 50, X=2. C. F(-5)=D. F(X)= -34, X=
nignag [31]

The given function is

f(x)=3x+2

A . f(4) means we have to evaluate the function when x = 4.

f(4)=3(4)+2=12+2=14<h2>Therefore, f(4) = 14.</h2>

B. f(x) = 50 means we have to evaluate the function when y = 50.-

\begin{gathered} 50=3x+2 \\ 50-2=3x \\ x=\frac{48}{3} \\ x=16 \end{gathered}<h2>Therefore, f(16) = 50.</h2>

C. f(-5) means we have to evaluate the function when x = -5.

f(-5)=3(-5)+2=-15+2=-13<h2>Therefore, f(-5) = -13.</h2>

D. f(x) = -34.

\begin{gathered} -34=3x+2 \\ -34-2=3x \\ x=\frac{-36}{3} \\ x=-12 \end{gathered}<h2>Therefore f(-12) = -34.</h2>
