Answer:
(a) SV/VW
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and sides in a right triangle. This problem also makes use of the properties of similar triangles:
- corresponding sides are proportional
- corresponding angles are congruent
__
<h3>sine ratio</h3>
The sine of angle U is given by ...
Sin = Opposite/Hypotenuse
The side opposite angle U in ΔTUS is ST. The hypotenuse of that right triangle is side TU. This means the desired ratio is ...
sin(U) = Opposite/Hypotenuse = ST/TU
<h3>corresponding ratio</h3>
In similar ΔVWS, angle W has the same measure as angle U. Its sine will be the ratio of the corresponding sides. The similarity statement ΔTUS~ΔVWS tells you that the side corresponding to ST is SV, and the side corresponding to TU is VW.
sin(U) = sin(W) = SV/VW
Answer:
93912/391
Step-by-step explanation:
-11-4 - (-b+3)
Distribute the negative sign
-11-4+b-3
Simplify like terms -11, -4, and -3, making sure to remember their sign.
-11-4-3 = -18
So the answer would be b-18 or -18+b.
Answer:
11/15 km
Step-by-step explanation:
Simply sum the areas:
2/5 + 1/3 = (6 + 5)/15 = 11/15
