X= 180 - (55 + [180 - 105])
x = 180 - (55 + 75)
x = 180 - 130
x = 50
Answer:
It has to be -9
Step-by-step explanation:
When you pull something to the negative power, it means that you find the reciporal (aka a fraction). So to make it to the power of 9 in the denominator, it must be a -9 in the numerator.
Hope this helps!!!

Answer:
The distance of the dot above the ground is 28.9 in
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
The triangle ABC is an isosceles triangle
CA=CB=15 in ------> is the radius of the circle
∠ACD+112°=180° ---> because the diameter divide the circle into two equal parts
∠ACD=180° -112°=68°
In the right triangle ACD
Find AD we have sin(68°)=AD/AC AD=AC*sin(68°) substitute the value AD=15*sin(68°)=13.9 in
Find the distance AB
AB=2*AD AB=2*13.9=27.8 in
The diameter is equal to
2*15=30 in
The distance of the dot above the ground is equal to
AB+(30-27.8)/2
27.8+1.1=28.9 in
