Answer:
13. x = 7 ; Converse : Alternate interior angles are equal .
14. x=12; Converse used : Linear pair
15. x = 23; Converse: Corresponding angles are equal
Step-by-step explanation:
13.
Refer the attached figure
Given: q || r
(Alternate interior angles )
So, 15x+3=108
15x=108-3
15x=105

x=7
So, x = 7 ; Converse : Alternate interior angles are equal .
14.
Refer the attached figure
Given q||r
(Alternate interior angles
So,
Now
(Linear pair)
So,7x-8+11x-28=180
18x-36= 180
18x=216

x=12
So, x=12; Converse used : Linear pair
15.
Refer the attached figure
Given q||r

(corresponding angles)
90+2x=5x+21
90-21=5x-2x
69=3x
23=x
So, x = 23; Converse: Corresponding angles are equal
Answer:
The mass of sun is 333333.33 times greater than the mass of earth
Step-by-step explanation:
Given as :
The mass of the sun =
kg
The mass of earth =
kg.
Let The mass of sun is x times greater than the mass of earth
i.e The mass of sun = x × The mass of earth
or,
kg =
kg × The mass of earth
Or, x = 
Or, x = 
∴ x = 333333.33
So, The mass of sun = 333333.33 × The mass of earth
Hence, The mass of sun is 333333.33 times greater than the mass of earth Answer
Answer:
b = 2A/h
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh where b is the base and h is the height
We want to find the base
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by the height
2A/h = bh/h
2A /h = b
b = 2A/h
