Answer:

Q.5 ab=cd

Q.6 ad=bc

Q.7 ce=ae

Q.8 eb=ed

Q.9 angle D=angle B (opposite angle of parallelogram are equal)

let other angle of parallelogram be x.

angle A+angle B +angle C + angle D= 360° (sum of quadrilateral is 360°)

x+130°+x+130°=360°

2x+260°=360°

2x=360°-260°

2x=100°

x=100/2

x=50°

Q.10 similarly, angle b= angle d

let other angle be x.

x+61°+ x+61°=360°

2x+122°=360°

2x=360°+122°

2x=238°

x=238°/2

x=119°

Q.11 in quadrilateral opposite angles are equal and opposite angle of parallelogram are equal.

What is the solution to the equation g/13=52<br><br> A.4<br> B.19<br> C.650<br> D.676
Alexxandr [17]

Answer:

g=676

Step-by-step explanation:

g/13=52

We simplify the equation to the form, which is simple to understand  

g/13=52

Simplifying:

+ 0.0769230769231g=52

We move all terms containing g to the left and all other terms to the right.  

+ 0.0769230769231g=+52

We simplify left and right side of the equation.  

+ 0.0769230769231g=+52

We divide both sides of the equation by 0.0769230769231 to get g.
