Answer:

AB= 20 feet

Step-by-step explanation:

Given triangle ABC is a right angle triangle

Use trigonometric ratio to find the length of the Side AB

AB is the hypotenuse

Sin = opposite side divide by hypotenuse

sin(B)= \frac{AC}{AB}

sin(30)= \frac{10}{AB}

Cross multiply it

sin(30) \cdot AB= 10

AB= \frac{10}{sin(30)}

AB= 20 feet

Find the last angle:
180-(30+90)
180-(120)
60

Evaluate using sine rule:
\frac{c}{sinC}=\frac{b}{sinB}

c=\frac{bsinC}{sinB}

=\frac{10sin90°}{sin30°}

=20

The length of line segment AB is 20 feet (answer choice C)

Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x game
belka [17]

Given :

Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today.

To Find :

Which equation can be used to find y, the total minutes Andrew will play video games today.

Solution :

Number of minutes he play after school time, n = 15x .

Number of minutes already played, c = 32 .

So, total number of minutes he play games for today is :

y = n + c

y = 15x + 32

Therefore, equation which is useful to find number of minutes video game played per day is y = 15x + 32 .

Igoryamba

Answer:

cos(\alpha)=\frac{3}{5}=0.6

cosec(\alpha)=\frac{5}{4}=1.25

Step-by-step explanation:

El cos(α) se define como el cociente entre el cateto adyacente y la hipotenusa.

El valor del cateto adyacente en nuestgro caso es CA = 3.

La hipotenusa se calcual de la siguiente manera:

h=\sqrt{3^2+4^2}=5

Por lo tanto, el cos(α) sera:

cos(\alpha)=\frac{3}{5}=0.6

El cosec(α)=h/CO.

El cateto opuesto CO = 4 y la hipotenusa h = 5

Por lo tanto, el cosec(α) sera:

cosec(\alpha)=\frac{5}{4}=1.25

Espero te haya sido de ayuda!

ale4655 [162]

Answer:

4p {}^{2}  + 4p \:  + 5p + 5

= )4p {}^{2}  + 9p + 5

= )4p {}^{2} +  (5 + 4)p \:  + 5

= )4p {}^{2}  + 4p \:  + 5p \:  + 5

= )4p(p \:  + 1) + 5(p \:  + 1)

p = - 1 , -5/4
