QUESTION: 1

In a parallelogram ABCD, if ∠A = 115°, then ∠B, ∠C and ∠D are

Solution:

In a parallelogram ABCD, ∠D = 115° (Given)

Since, ∠A and ∠D are adjacent angles of parallelogram. 

We know, Adjacent angles of a parallelogram are supplementary. 

∠A + ∠D = 180° 

∠A = 180° – 115°  = 65° 

Measure of ∠A is 65°.

QUESTION: 10

Perimeter of a parallelogram is 22 cm. If the longer side, measures 6.5 cm, the measure of the shorter side will be:​

Solution:
Let the length of the shorter side be x cm
length of longer side= 6.5 cm
perimeter= 22 cm
>2[sum of adjacent sides]=22
>2[longer side+shorter side]=22
>2[6.5+x] = 22 = 22/2 =11
>6.5 + x =11 = 11 - 6.5 = 4.5
> x= 4.5
QUESTION: 11

In the figure ABCD is a square. A line segment DX cuts the side BC at X and the diagonal AC at O such that ∠COD = 105° and ∠OXC = y. Then y is equal to

Solution:
Given :In the figure ABCD is a square. A line segment DX cuts the side BC at X and the diagonal AC at O such that COD = 105 degree and OXC = y
To find :y 
Since DX is a line segment, then 
angle COD + angle COX = 180 degrees {Angle sum property}
=> angle COX = 180 -105 = 75 degrees..(1)
Since ABCD is a square and AC is a diagonal , therefore all the angles in a square is 90 degree each and AC bisects the angle in half. {property}
=> angle ACB {  also OCX } = 90 /2 =45 degrees...(2)
In traingle COX 
=> angle OCX + angle COX  + y = 180 degree { sum of angles in a triangle is 180 degree}
=> y = 180 - (45+75) {using eq 1 and 2}
=> y = 60 degrees Answer
