m∠R = 27.03°
Solution:
Given In ΔQRP, p = 28 km, q = 17 km, r = 15 km
To find the measure of angle R:
Law of cosine formula for ΔQRP:

Substitute the given values in the above formula.



Switch the given equation.

Subtract 1073 from both side of the equation.

Divide by –952 on both sides.



Hence m∠R = 27.03°.
If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area<span> is labeled, then you do not need to know the apothem. Just take the </span>area<span> of that one triangle, and multiply by the number of sides in the original </span>polygon<span>.</span>
Well, it depends if its positive or negative. 2 positive integers will equal a positive, 2 negatives will equal a negative. A negative and a positive will depend.
Answer:
x1.20
y0.75)
Step-by-step explanation:
you have to simplify
3+-4=-1
3-4=-1
-1=-1
so the answer is:
-1 = -1
