What is the cot in simplest fraction form???? Please help been stuck for 30 minutes!!

Fantom [35]

Answer:

65/72

Step-by-step explanation:

cot is simply cosine over sine or the tangant flipped

the cos (c)=65/97

sin (c) = 72/97

cot would be (65/97)/(72/97)

How do you divide fractions? By multiplying the reciprocal!

cot would be 65/97 * 97/72

the 97s cross out.

65/72

Simple geometry please help Find KL. Round to the nearest hundredth.

vivado [14]

Answer:

KL ≈ 1.94

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos48° = $\frac{adjacent}{hypotenuse}$ = $\frac{JL}{KL}$ = $\frac{1.3}{KL}$ ( multiply both sides by KL )

KL × cos48° = 1.3 ( divide both sides by cos48° )

KL = $\frac{1.3}{cos48}$ ≈ 1.94 ( to the nearest hundredth )

Can someone please help me with 10-16 it’s due tomorrow!!! Please

VMariaS [17]

10) V=πr² *h= π*10²*12≈3770
11) V=A(base)*h= (3√3/2)*(9²)*10=2104
A(base)=(P*a)/2=(6*9*3√3)/2=9*9*3√3/2

12)V=πr² *h=π*18² *6≈6107
13)V=4*3*12=144
14) h(triangle)=√(5²-3²)=√16=4
A(base)=(3*4)/2=6
V=A(base)* height (prism)=6*2=12
15) V=A(base)*h= (3√3/2)*(6²)*11= 1029
16)V=A(base)*h=2(1+√2)5²*22≈2656

The hypotenuese of an isosceles right triangle is 13 inches. The midpoints of its sides are connected to form an inscribed trian

Georgia [21]

Answer:

The Sum of the areas of theses triangles is 169/3.

Step-by-step explanation:

Consider the provided information.

The hypotenuse of an isosceles right triangle is 13 inches.

Therefore,

$x^2+x^2=169\\2x^2=169\\x=\frac{13}{\sqrt{2} }$
