Answer:
A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.
(this may be more of an architect's job, as they are the ones that design the houses)
or
An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
Answer:
the angle sum of quadrilateral is 360 degree
x+2x+3x+4x = 360
10x=360
x= 360/10
x= 36
1 angle= 36
2 angle= 2*36=72
3 angle =3*36=108
4 angle= 4*36= 144

Step-by-step explanation:
Check attachment for solution and better understanding
AC and BC are tangent, then AC and BC will form a right angle with the radius of the circle
Given that,
EC = 20in
And Radius = 26in
Find AC and BC.
Though AC and BC are similar.
Taking Triangle ADC, check attachment, it is a right angle triangle.
Since it is a right angle triangle, we can apply Pythagoras theorem
DC² = AD² + AC²
46² = 26² + AC²
46² - 26² = AC²
AC² = 1440
AC = √1440
AC = 37.95 in
Also, taking triangle DBC
DC² = DB² + BC²
BC² = DC² - DB²
BC² = 46² - 26²
BC² = 1440
BC = √1440
BC = 37.95 in
First of all 5-(-8) is the same thing as 5+8. So you would add 5+8=13
