1-In the statements below find which is True and which is False
2-Given , verify that the area
and find the value of S when x=300 .
3-The angles of a triangle are 450 dhe 750 . Find the measure of the third angle in radian .
Find the third angle in degrees 1800-(450+750)=600.Then plug in . The third triangle is
4-Find the domain of the function . Answer:
5-Verify the indentity. .
Answer
6- Given b=2;
; dhe β=450 in the picture, find the angles γ and α.
Based on the sin theorem we can write
7-Given triangle with a=5cm; b=6cm dhe c=7cm find the Area(S) of the triangle..
Find the radius of the circumcenter of the tringle. Find the sin and cos of the angle α.
. We can find the area by using Heron Formula
.
From the sin theorem we write: . From the cos theorem we write :
.We can see that the angle is an acute angle.
8-In the triangle ABC there are givenb=4;
; α=450.Find: the side a; sinβ ; sinγ; the height of the triangle taken from the C apex .
Using the cos theorem we can find the side a. . Using sin theorem we can find sinβ dhe sinγ.
To find the height of the triangle taken from the C apex , first we can find the area of the triangle S. We also know that
. where h is the height of the triangle taken from the C apex.
