87
You can add up the angles that are labeled(73,110,and 90 because of the right angle) and get 273.
For a quadrilateral, all of the angles add up to 360.
So, subtract 360-273.
You get 87.

Answer:
<h3>p = 131.25</h3>
Step-by-step explanation:
The variation p varies directly with T is written as
p = kT
where k is the constant of proportionality
To find p when T =500 we must first find the formula for the variation
That's
when p = 105 and T = 400
105 = 400k
Divide both sides by 400
<h3>

</h3>
So the formula for the variation is
<h2>

</h2>
when
T = 500
Substitute it into the above formula
That's

Simplify
The final answer is
<h3>p = 131.25</h3>
Hope this helps you
Perpendicular lines have slopes that are negative reciprocals. example: line a has a slope of 2/3, line b has a slope if -3/2 if they are perpendicular.
Answer:197.8
The formula for a cylinder is 3.14*r^2*h but if you don't round to the nearest tenth the the answer is 197.82034.
Step-by-step explanation:Step one mutiply 3^2=9, Step two mutiply 3.14*
9=28.26, Step three mutiply 28.26*7=197.82.But if you round 197.82034 to the nearest tenth which is moving one decimal place to the right you'll will get 197.8.
