we can have a triangle and we know that there are two angles.
30º and a 45º + 105 =180º angle. applying the sides.
therefore if we have the whole triangle completed we have a constant triangle.
so it tell us we can you’se SOH CAH TOA
we can varrify what kind of triangle we are using.
for example if we were to use Sin I would do
Sin 30/ 2 = sin of 105º/ A = sin=45º/ B
if you would want to solve for sin 30/2 and sin 105, then we solve.
or Sin 30/2 and Sin 105 as well.
with your calculator use sin= 30=.5 and use sin 105º a divide by 1.5 on both sides 1.5= A /sin 105º * 1.5 answer would be 3.86. a is = to 3.86 (Not the answer)
Answer:
yes
Step-by-step explanation:
you have to use trigonometry to find the area of a parallelogram without the height.
the formula is: Area = ab(sin(x))
Where a and b are the length of parallel sides and x is the angle between the sides of the parallelogram.
First you wanna Solve for a to make your answer:
a <span>≤ 1
Then just graph:</span>
Hi
This is really easy you just have to add and subtract 3 from 3
12+3=15
12-3=9
But I notice on the answers their is -15 and -9 so if your doing absolute value you do it like this |-12|=12 so also -9 and -15.
Let me know if this helps!
