Answer:
True
m∠T = 40.4°
Step-by-step explanation:
We know all the sides of the triangle but we do not know any of its angles.
To find out if the angle T = 40.4 ° we use the cosine theorem.
According to the cosine theorem:

Where
is the angle between a and b.
In this case:

Then we clear α from the formula and verify that it is equal to 40.4 °

Answer:
3.141
Step-by-step explanation:
just find area of full circle which is 12.566 then divide by 4 (its pi)
Answer:
F = 105
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is (n – 2)180.
This polygon has 6 sides so the sum of the interior angles is (6-2) * 180 =
720
Add up the angles
x-60 +x-40 +130 +120 +110 + x-20 +x-20 = 720
Combine like terms
4x +220 = 720
Subtract 220 from each side
4x+220-220 = 720-220
x = 500
Divide each side by 4
4x/4=500/4
x = 125
We want to find angle F
F = x-20
= 125-20
105
Answer:
80%
Step-by-step explanation:
Percent increase is calculated as
× 100%
Increase = $27 - $15 = $12 , then
percent increase =
× 100% = 0.8 × 100% = 80%
