plz answer first answer = BRAINLIEST. also show how you have done​

Answer 1

SOLUTION :

Let the measure of A be x°

So, Measure of B will be (x + 50)°

We know that,

The sum of supplementary angles of a parallelogram is 180°

So,

A + B = 180

x + (x + 50) = 180

2x = 180 - 50

2x = 130

x = 130/2

x = 65

Hence, the value of A is 65°

• The value of B is = (65 + 50)°
• = 115°

Answer 2

Answer:

65 degrees

Step-by-step explanation:

Let angle A be x,

then, angle B is x+50.

Opposite angles of parallelogram are equal.

Therefore, angle C = x and D = x+50.

Also,

sum of all angles of a  parallelogram are 360.

so, x+x +(x+50)+ (x+50) = 360

So, 4x + 100 = 360

x = 65 degrees

Therefore, angle B = 65 + 50 = 115 degrees
