a) value of x:
ZX =(10x+9)°
122°=( 10x+9)
122 - 9= 10x
113= 10x
x = 113/10= 11.3 °
so answer is = 11.3°
b) measure of Arc XZ :
formula to find Arc= © angle÷360 x 2πr
A = 122÷360 x 2πr
A = 61/180x 2πr
A = 0.3388x2πr
A= 0.6776πr
Answer:
0
Step-by-step explanation:
The opposite of 12 is -12, and 12+(-12)=12-12, or 0.
Answer:
The dimension of the cardboard is 34 cm by 34 cm by 17 cm.
Step-by-step explanation:
Let the dimension of the cardboard box be x cm by y cm by z cm.
The surface area of the cardboard box without lid is
f(x,y,z)= xy+2xz+2yz.....(1)
Given that the volume of the cardboard is 19,652 cm³.
Therefore xyz =19,652
......(2)
putting the value of z in the equation (1)
The partial derivatives are
To find the dimension of the box set the partial derivatives 
and 
.Therefore 
.......(3)
and 
.......(4)
Now putting the x in equation (3)
⇒y=34 cm
Then 
=34 cm.
Putting the value of x and y in the equation (2)
=17 cm.
The dimension of the cardboard is 34 cm by 34 cm by 17 cm.
Answer:
n=23/10
Step-by-step explanation:
10(n+4)=63
n+4=63/10
n=63/10-4
n=23/10
decimal form: 2.3
