Answer:
height ≈ 11.9 units
Step-by-step explanation:
Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.
Using the sine ratio in one of these right triangles, then
sin48° = ( the opposite is the height h )
sin48° = ( multiply both sides by 16 )
16 × sin48° = h , thus
h ≈ 11.9 ( to the nearest tenth )
For question 39 & 40, we need to use the below equation to complete the sentence
Question 39:
When ' n ' increase, the will also increase and that multiplied with constant ' m ', the l will also increase.
Solution for question 39:
As increases and
stays constant ,
<u>increases</u>
-------
Question 40:
Solving the equation for m, we get
When ' l ' increases, the numerator increase, the denominator stays constant because 'n' stays constant, for this condition, the fraction increases.
Solution for question 40:
As increase and
stays constant,
<em><u>increases</u></em>
