Answer:
8) 10°
9) X can not be determined.
10) 10°
11) 12 units.
Step-by-step explanation:
8) The three sides of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each angle will be 60°.
So, 6x = 60°
⇒ x = 10°.
9) The three angles of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each side will be equal.
So, 6x - 5 = 6x
So, x can not be determined from this equation.
10) Δ KLM is equilateral, so, KN will bisect ∠ MKL. So, ∠ NKL = 30°
Hence, 3x = 30°
⇒ x = 10°
11) In Δ XYZ, XZ = XY , so, ∠ Z = ∠ Y.
Again, ∠ X is given to be 60°.
Therefore, each angle is 60°.
So, the triangle XYZ is equilateral, and each side will be equal.
So, 3x + 8 = 4x - 4
⇒ x = 12 units. (Answer)
Answer:
The measure of the side 
is 8.8.
Step-by-step explanation:
Since 
, then 
, 
, 
and 
. From figure we have the following relationship:
(1)
Where 
is the proportionality ratio.
If we know that 
, then the measure of side is:
(1b)
(1c)
The measure of the side is 8.8.
Answer:
5/8 are spelled incorrectly
Step-by-step explanation:
There are 16 words
He spelled 6 correctly
That means he spelled 16-6 = 10 incorrectly
The fraction spelled incorrectly is wrong/total
10/16
Simplify by dividing the top and bottom by 2
5/8
Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
