Answer:
-6 because I did it on my calculator
The halves of the rhombus separated by line BD are equilateral triangles.
∠BAD = 60°
so
∠ADM is 0.80*60° = 48°.
∠BMD is an exterior angle to ΔAMD, so is equal to the sum
∠BMD = ∠BAD + ∠ADM
= 60° +48° = 108°
∠BMD = 108°
Answer:
Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.
Step-by-step explanation:
What is sine? The sine of an angle x is the length of the opposite side.
What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
What is tangent? The tangent of an angle is the length of the opposite side
Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.
Answer: x=y-1
Step-by-step explanation:
Answer:
P = 20.
Step-by-step explanation:
Given that:
the variable that is not given is P. So to find out P, we substitute the two given values into the equation as following:
P= 2L + 2W
<=> P = 2(6) + 2(4)
<=> P = 12 + 8
<=> P = 20.
Hope it will find you well.
