ANSWER:
tan(30⁰)=√3/3
cos(30⁰)=√3/2
<h3>switch sides:</h3>
sin(x) /√3/2 =√3/3
<h3>multiply both sides by 3:</h3>
3·sin(x) /√3/2 =3·√3/3
<h3>simplify:</h3>
2√3 sin (x) =√3
<h3>divide both sides by 2√3:</h3>
2√3 sin (x) / 2√3 = √3 / 2√3
<h3>simplify: </h3>
<u><em>sin (x)= 1/2</em></u>
Answer:
26.14
Step-by-step explanation: Just subtract.
Answer:
It is indeed 63
Step-by-step explanation:
The easy way to go about this is to recognize that if the triangles are similar, the ratio between the similar sides will be the same.
Notice:
4/5 = 36/45
So:
4/7 should = 36/x
If:
4/7 = 36/x
4x/7 = 36
4x = 36*7
x=36*7/4
x=63
Answer:
No
Step-by-step explanation:
24+19+30=73 not 90
