Question

Pls do help me guys.... Best answer will be marked as Brainliest!!!!!

Answer 1

1] 45°,45°

2]180°-105°=75°

3]180°-100°=80°[SINCE LINEAR ANGLE=180°]

4]75°=30°+X°

X=45°[CORRESPONDING SIDES ARE EQUAL]

5]90-[90-a]=a

Answer 2

Answer:

1.) (a):- 45

2.) (b):- 75

3.) (d):- 80

4.) (a):- 45

5.) (a):- a

Step-by-step explanation:

ANS:-1 : In a right angle triangle, right angeled at A if AB=AC, then the two corresponding angels will be equal (i.e. angle B = angle C) . So,

angle(B+C)=180-90

angle(2B)=90

angle(B)=45.

ANS:-2 : let x be a no.

so, supplement of x is 180-x.

so supplement of 105 is 180-105

which is equal to 75.

ANS:-3 : linear pair of x is 180-x.

so linear pair of 100 is 180-100

which is equal to 80
