Answer:
b=204
Step-by-step explanation:
The law of sine states that:
We know that a triangle has 180° total, so we can subtract the two angle measures we know to find the third angle: °.
Using these two things, we can come up with the equality , which we can use to solve for side b.
, so we know that
.
Next, we would multiply both sides by b to get .
Sin49°≈0.75471, so to find b we would multiply 0.75471×270=203.77
Since the problem asks us to round to the nearest whole number, b=204
Hope this helps! :)
Answer:a) a=22, b=11
b) m=7, n=
Step-by-step explanation:
You should use trigonometry ratios as required and then you should use pythagoras theorem
In a) cosine(30°)= base/hypotenuse,
where 11√3 is the base
"a" is hypotenuse and
"b" is perpendicular
from this you can find the value of perpendicular then you should use pythagoras theorem to find the value of hypotenuse
pythagoras theorem is
base²+perpendicular²= hypotenuse²
Same is applied on (b) right triangle as, sine(45°)=perpendicular/hypotenuse
