Answer:
2.54. Calculate the approximate value:2.6 *
Step-by-step explanation:
Note, since both factors have the same denominator, we can add the numerators together.
Numerator :
5n + (2m + 4n) = 5n + 2m + 4n = 9n + 2m
Denominator :
30m
Thus,
= (9n + 2m) / 30m
ANSWER
C) Triangle
EXPLANATION
Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
We use the sine rule and cosine rule to find the missing sides and angles.
If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.
8 is 6.2
9 is 7
The pattern here is +0.8.
4.6 - 3.8=0.8
5.4-4.6=0.8, and so on
