Answer:
D.
Step-by-step explanation:
Reference angle = 45°
Length of Opposite side = x
Hypotenuse length = 5
Applying trigonometric ratio, we have:
Multiply both sides by 5
(sin 45 = 1/√2)
Rationalize
Answer: with the power of 9 − 1 with the power of 6
Sorry if im wrong and have a wonderful day!!!!!
A is true, because if you cross multiply the two fractions, you get 36 = 36. if you cross multiply the other proportions, none of them are equal except A.
Answer:
the answer is nonagon
A nonagon is a polygon made up of 9 sides and 9 angles.
When two triangles are similar, they're sides are in proportion.
In order to find the unknown side, we first have to find the ratio of the larger triangle to the smaller triangle.
We can use the sides TV and LN to make the proportion.
=
The ratio between the two triangles is 21:6
Now we can solve for the unknown side.
=
Cross multiply:
8 * 21 = 6 * LM
168 = 6LM
Divide both sides by 6:
LM = 28
The unknown side's length is 28 centimeters
Good luck!
