Question

Which equation could be used to find the measure of one acute angle in the right triangle shown below?
A. sin A equals 4 over 5
B. tan A = 5 over 4
C. cos B = 5 over 4
D. tan B = 4 over 5

Answer 1

@satellite73 can you help me?

Answer 2

SOH CAH TOA

Answer 3

sin - O/H
cos - A/H
tan - O/A

Answer 4

Does this look familiar?

Answer 5

oh

Answer 6

somewhat but not really i think i have to use cos

Answer 7

cosB = \(\frac{adj}{hyp}\) does that equal \(\frac{5}{4}\)?

Answer 8

i think so?

Answer 9

oh wait yeah it is

Answer 10

Adjacent means next to
Opposite means across from
Hypotenuse means the longest side opposite the right angle.

Answer 11

Which one is the Hypotenuse?

Answer 12

opp of C 5

Answer 13

Yes. So, unless you are using tan -> the denominator must be 5.

Answer 14

so it i 5 over 4

Answer 15

5 is the length of the hypotenuse

Answer 16

so it must be sin A

Answer 17

Numerator -> N=north
Denominator ->d=down

Answer 18

Yes.

Answer 19

oooh thanks
