Let's make another angle y
Where y= 51° (corresponding angles )
and x+y= 180°. ( linear pair )
x+51°= 180° (y=51°)
x=180°-51°
x= 129°
<u>So the value of x is 129</u>°
Hope you got your answer !
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =
= 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =
≈ 88.2
