For each left handed person there is about 4 right. So there are about 23 right handed and 7 left handed
In a kite, the diagonals intersect normally. Hence, we also know that XV= 4cm, half of XZ. This is because the triangle XVY and XVW are equal, but it is a general property of kitest. XVY is the right angle in this. We can use then trigonometry to calculate VY.
We have that tan30= opposite site of angle XYV/adjacent leg by the definition of the tangent. Hence tan30= XV/YV. Thus, substituting the value of the tangent:
Answer: x4+13x2+36=0
Step-by-step explanation:
Let's solve your equation step-by-step.
x4+13x2+36=0
Step 1: Factor left side of equation.
(x2+4)(x2+9)=0
Step 2: Set factors equal to 0.
x2+4=0 or x2+9=0
Answer:8.8 servings
Step-by-step explanation:
2/25 times 1 1/10 is about 8.8
Answer:
see explanation
Step-by-step explanation:
(a)
(the side required )² = sum of squares of other 2 sides - ( 2 × product of other 2 sides and cos(angle opposite side required ) )
x² = 12² + 15² - (2 × 12 × 15 × cos71°)
(b)
x² = 144 + 225 - 360cos71°
= 369 - 360cos71° ( take square root of both sides )
x =
≈ 16 cm ( to the nearest integer )
