The area of a rhombus can be computed from its side (s) and angle (θ) by
.. A = s^2*sin(θ)
For your numbers, this is
.. A = (12 cm)^2*sin(60°) ≈ 124.7 cm^2
Answer:1. The measure of angle P is 53. 2. The value of x is 25.
3. The length of each side of the triangle is 30 cm.
Step-by-step explanation:
1. (3x +2) + (3x + 2 ) + (5x -11) =180 Angle Q and P have the same measures because it is an isosceles triangle that is why you have three expressions.
So x =17 and 3(17)+ 2 =53
2. (2x +10) + (2x+10) + (2x + 10)= 180 this is because the second triangle is an equilateral triangle which means all it have the same measures.
solve for x. and x is 25.
3.The third triangle is also an equilateral triangle so you will make the expressions equal each other and solve for y .
1/10y + 11= 3/5y -4
y= 30
Answer: A. 1.2
Step-by-step explanation:
Given : Sample size : n= 64
Standard deviation: 
The formula to find the standard error of mean is given by :-

Therefore, the standard error of the mean= 1.2
Hence, A is the right option.
