Answer:
140,120
Step-by-step explanation:
sum of angles in a quadrilateral =360
sum of the 1st two angles=60+40=100
360-100=260
the ratio of the remaining angles 7:6
therefore:

=140
for the second angle
260-140=120
Answer:
26.4
Step-by-step explanation:
<u>Law Of Cosines:</u>

This should work for any side. This can generally be thought as:

If this is too confusing here's the formula for the other sides (which is essentially the same, just different variables)


Anyways now just plug in the known values into the equation

Square and multiply values

Add the values in the numerator

Take the inverse of cosine on both sides

calculate arccosine (inverse cosine) using a calculator

Round to nearest tenth

ANSWER
36 .19
EXPLANATION
We want to estimate

This is the same as

or

We multiply the numerators to get,

We convert to decimals to get
