Answer:
Option A) m∠RNS=27°
Step-by-step explanation:
We know that
∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:
∠RNS = 
∠SNT= 
∠TNU= 
Now let us add all the angles and solve for the value of
as follow:


Now lets plug in the value into the expression for angle
∠RNS to find the angle as:

Thus Option A. is the correct answer.
The product of two numbers is the result of multiplication.
so 10.04 • 2.8
= 28.112
Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2
1. w=2
2. x=2
3. y=-5
4. a=1
