Question

find x with explanation.​

Answer 1

Step-by-step explanation:

1. 50°

2. 65°

3. 60°

4. 60°

Answer 2

Answer:

iii) 110°+30°+x=180° {°•° sum of all angles in a triangle add up to 180 , and note its the same for all the sum here also called as ASP rule)

=> 140+x=180

=> x=180-140

=> x=40°

iv) x+x+50°=180°

2x= 180-50

x= 130°/2

x= 65°

since both the angle are equal

•°• x=x=65°

v) x+x+x=180°

3x=180°

x=180°/3

x=60°

all the three x's hv the same value for the angle

i.e x=x=x=60°

vi)2x+x+90°=180°[ the angle opp to hypotenus in a right angled triangle is always 90°]

3x+90=180

3x=180-90

x=90/3

•°• x=30° and 2x = 2(30)=60°

leave a like if u get it ..plss mark the answer as brainlest
