Answer:
<h2>BR ≈ 49.0</h2>
Step-by-step explanation:
Use cosine:
We have
Substitute:
<em>cross multiply</em>
<em>divide both sides by 8,572</em>
Answer:
its the 3rd choice.
Step-by-step explanation:
Firstly, we find angle BDC (180-90-30=60)
Now that we found it we can use the sine rule to find DB (which i put as an x), which is sin60/14=sin30/x, by cross multiplication, we find that its equal to a decimal number, i will use its root version to this easier, its equal to 14sqrt3/3 inches.
And now we use the pythagorean theorem to find DC, we find that it is equal to 28sqrt3/3
Now, we find angle BAC (180-90-(30+15)=45)
Again, we use the sine rule to find AB (whom i will refer to as x and from whom we will subtract DB to find the length of AD), so we cross multiply in sin45/14=sin(30+15)/x, it is equal to 14.
So since AB-DC=AD
14-(14sqrt3/3)= 5.917096231 (and we ound that to a 5.9)
Answer:
If Z is the centroid of RST , RZ = 42, ST = 74, TW = 51, ZY = 23 and find each measure. 4. If E is the circumcenter of MNP , find each measure. If Z is the centroid of RST , RZ = 42, ST = 74, TW = 51, ZY = 23 and find each measure. 4. If E is the circumcenter of MNP , find each measure.
