Question

Find x in these 30 - 60 - 90 triangles.
X=?

Answer 1

\[\sqrt{?}\]

Answer 2

understand that

Answer 3

yes

Answer 4

so x√3 = 7

Answer 5

is that the final answer?

Answer 6

find x from that

Answer 7

so x = 7/(√3)

Answer 8

why?

Answer 9

to get x from x(√3) = 7 divide both sides by (√3)

Answer 10

oh okay now I understand

Answer 11

how would you find Y?

Answer 12

now that you know that x = 7/(√3)
y = 2x = 2(7/(√3)) = 14/(√3)

Answer 13

thank u so much I understand when you explain it

Answer 14

your welcome :)

Answer 15

Find x in these 45 - 45 - 90 triangles.
x=?

Answer 16

understand that

Answer 17

yes

Answer 18

so 8 = x(√2)

Answer 19

then find x by dividing both sides by (√2)

Answer 20

\[8/\sqrt{2}\]

Answer 21

yes :)

Answer 22

my teacher confuses me but with you I'm catching on

Answer 23

Solve these proportions.
x=

Answer 24

miltiply both sides by (x/1)

Answer 25

once I do that what would I do next

Answer 26

multiply both sides by 4

Answer 27

then square root both sides

Answer 28

\[4\sqrt{3}\]

Answer 29

close... √12 = √(4*3) = √4 * √3 = 2√3

Answer 30

Enter the trigonometric equation (sin, tan, or cos) you would use to find x in the following right triangles. Do not solve the equations.

Answer 31

understand that when

sin(x)= (opposite/hypotenuse)
cos(x) = (adjacent/hypotenuse)
tan(x) = (opposite/adjacent)

Answer 32

yes

Answer 33

the question asks to find the length of the side opposite of the angle 70
and also gives you the value of the hypotenuse of the right triangle.
so what sin, cos, or tan equation should you use given the opposite and hypotenuse?

Answer 34

yes

Answer 35

sin

Answer 36

correct :)

Answer 37

how do you use the equation

Answer 38

to use it in context of the problem,
sin(70)=x/8 then multiply both sides by 8 to get x alone

Answer 39

Find x in this 45°-45°-90° triangle.
x=

Answer 40

understand that
