QUESTION 1
We can use the cosine rule to find the missing side length.
Recall that the cosine rule for a triangle with sides a,b,c and an included angle A is
Let the missing side length in the triangle with sides 6, 9 and the included angle of be units.
We then substitute the values into the cosine rule to obtain;
units to the nearest tenth.
QUESTION 2
We again use the cosine rule:
We substitute the given values to obtain;
to the nearest tenth
QUESTION 3
We again use the cosine rule :
to the nearest hundredth
You divide fractions by changing the using the reciprocal of the right side of the fraction then mutiply both of them and simpfly.
Ex: 4/5 ÷ 3/2
4/5 × 2/3 = 8/15
(x + 9 )/2 = 3x
x + 9 = 6x
5x = 9
x = 9/5
