Y= 54 degrees


explaination: triangle angles = 180 degrees
So
180-72(the angle you already have)
108 then divide by 2 because that is how many more angles you have and you get 54.

Rus_ich [418]

primero vamos a calcular el lado faltante usando el teorema de pitagoras para poder obtener el lado faltante a

a=\sqrt[]{hipotenusa^2-cateto^2}a=\sqrt[]{100^2-85^2}=52.68

a=52.68 m

teniendo el lado faltante podemos calcular las razones trigonometricas

\sin (55)=\frac{85}{100}=0.85\cos (55)=\frac{52.68}{100}=0.52\tan (55)=\frac{85}{52.68}=1.61

\csc (55)=\frac{100}{85}=1.17\sec (55)=\frac{100}{52.68}=1.89\cot (55)=\frac{52.68}{85}=0.61

Find the value of x<br><br>d:6​
Phantasy [73]

\sf{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve for x ~

\qquad \sf  \dashrightarrow \: 5x = 3x + 12

[ by vertical opposite angle pair ]

\qquad \sf  \dashrightarrow \: 5x - 3x = 12

\qquad \sf  \dashrightarrow \: 2x = 12

\qquad \sf  \dashrightarrow \: x = 12 \div 2

\qquad \sf  \dashrightarrow \: x = 6

Therefore, the correct choice is D. 6

What is y when x is 893?
garik1379 [7]

The computation shows that the value of y when is 893 will be 1339.5

<h3>How to compute the value?</h3>

It should be noted that when x is 2 y is 3.

Therefore, the value of y when x is 893 will be

= 893 × 3/2

= 1339.5

Therefore, the value of y will be 1339.5

Emily and Molly are selling pies for a school fundraiser. Customers can buy cherry pies and lemon pies. Emily sold 4 cherry pies
Natalka [10]

Answer:

<h2>cherry pie = 5</h2><h2>lemon pie =10</h2>

Step-by-step explanation:

Step one:

let cherry be x

and lemon be y

the systems of the equation for the solution is given as

4x+y=30-----------1

8x+6y=100------2

Step two:

solve the equation simultaneously by substitution we have

4x+y=30

y=30-4x

put y=30-4x in equation 2

8x+6(30-4x)=100

8x+180-24x=100

8x-24x=100-180

-16x=-80

x=80/16

x=5

put x=4 in y=30-4x

y=30-4(5).

y=30-20

y=10
