Here is your answer
12m-6
REASON:
6(2m-1)
Multiply 6 with both the terms in bracket, we get
6×2m - 6×1
= 12m-6
HOPE IT IS USEFUL
180 degrees= a whole line
180-102=78
So m13 should equal 78°
To find the area of an obtuse triangle you have to multiply the base of the triangle by the vertical height and divide the result by 2 following the formula:

The base of the triangle is b= 7 miles and the height is h= 8 miles, using these lengths calculate the area as follows:

The area of the triangle is 28 square miles.
Answer:



Step-by-step explanation:
step 1
Find the length side a
Applying the law of cosines

substitute the given values



step 2
Find the measure of angle B
Applying the law of sines

substitute the given values



step 3
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values



5 37/100
5 is the whole part and you have 37 hundredths
