Question

In the parallelogram JMLK given below
Find the measure of angle JML. Give reason to support your answer.

Answer 1

Answer:

first supplement of angle M & J

Value of supplement equal to 180 degree

We take angle M equal to X

X = 180 - (2x + 30°)

X = 180 - 2x + 30

X + 2x = 180 - 2x + 30 + 2x

3x = 180 + 30

3x/3 = 210/3

X = 70

Answer 2

Answer:

70°

Step-by-step explanation:

Opposite angles of llgm are equal(Property of llgm)

then we can say that (2x+30)=(3x-10)

then

x=40°

then 2x +30= 110°

and 3x-10=110°

Now all angles of llgm adds up to 360°

We already obtained 220°

therefore addition of remaining angles is 360-220 = 140°

Now as I said the opposite angles of llgm are equal

so dividing this no by 2 will give me the ans

Hence angle JML= 140/2= 70°

and also angle JKL=70°(extra)
