Question

Help me please

Answer 1

do you know SOH CAH TOA ?

Answer 2

yes is it a^2 + b^2 = c^2

Answer 3

a^2 + b^2 = c^2
is good to know. It is the pythagorean theorem.

I mean SOH CAH TOA which is short for
SIN Opposite / Hypotenuse
COS Adjacent / Hypotenuse
TAN Opposite/ Adjacent

Answer 4

ok

Answer 5

See

when you have time

Answer 6

even If you don't know any trigonometry, notice that the hypotenuse is the longest side in a right triangle. No side is longer than it... which means x can't be bigger than 11
that means you can rule out two of the choices.

Answer 7

so b and d is not the answer

Answer 8

To do the problem, look at the angle labeled 20.

Next, we give names to the 3 sides. the hypotenuse is the longest side, and it is opposite the 90 degree angle. It is labeled 11
the side opposite the 20 degree angle is unlabeled.
the side adjacent to the 20 degree angle is labeled x

Answer 9

what 2 sides will we use ? The ones that are labeled.

Answer 10

what are the names of the sides we will use ?

Answer 11

is my answer c

Answer 12

what are the names of the sides we will use ?

Answer 13

opposite and adjacent

Answer 14

re-read this
opposite the 90 degree angle. It is labeled 11
the side opposite the 20 degree angle is unlabeled.
the side adjacent to the 20 degree angle is labeled x

Answer 15

ok well i dont knw what sides we looking for is it long leg short leg or hypotenuse

Answer 16

the question asks " what is the value of x"
that means they want the length of the side labeled x

Answer 17

ok

Answer 18

what are the names of the sides we will use ?

Answer 19

the 3 names we use are hypotenuse, opposite and adjacent.
we will want to use the sides that we know the length of, or want to know the length of.
