A. side AB = 38/3 units B.m∠VYX =77°
Step-by-step explanation:
A.A rhombus has its four sides equal. This means side AB=side CD
Given that AB=5x+1 and CD=2x+8 equate the two sides to find value of x as;
5x+1=2x+8
collect like terms
5x-2x=8-1
3x=7
x=7/3
side AB = 5x+1
AB= 5*7/3 +1
AB=35/3 +1
AB=35/3 +3/3 = 38/3
B.
The diagonals of a rhombus intersect to form 90°
Hence
(3n²-0.75)°=90°
3n²=90°+ 0.75°
3n² =90.75° -----dividing by 3 both sides
n² =90.75°/3 =30.25°
n²=30.25°
n=√30.25°
n=5.5°
so angle Z =90°
and angle ZVW =(9n+2)°
∠ZVW = (9*5.5 +2 )° =51.5°
In a rhombus all four sides are equal, thus side VY = YX.This means triangle VYX is an isosceles triangle.
Hence angle ∠YVZ=∠WVZ =51.5°, and because VYX is an isosceles triangle then ∠YXV =51.5° so
∠VYX= 180°-(51.5°+51.5°)
=180°-103°=77°

A)2:6
I think that is the answer
3x/2 units to the right, so b).
It's not c) or d), because the -3x/2 is within the sin, rather than outside like y=sin(x)-3x/2
If it were shifted to the left, the equation would be y=sin(x+3x/2)

Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.
So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.
You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.
You get 3/1 × 1/1 = 3
It equals to 3
Then, 4(2.6) = 4 × 2.6 = 10.4
2(-3) = +2 × (-3) = -6
When you multiply a positive number for a negative one, you'll always get a negative number.
Sum all the results.
3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4
Final answer: -13,4
