Answer:
a = - 2
Step-by-step explanation:
calculate the slope of the 2 given points and equate to 0.75
m = 
with (x₁, y₁ ) = (4, a ) and (x₂, y₂ ) = (8, 1 )
m = 
= 
then equating
= 0.75 ( multiply both sides by 4 to clear the fraction )
1 - a = 3 ( subtract 1 from both sides )
- a = 2 ( multiply both sides by - 1 )
a = - 2
It is the most important because it is used in many different things, such as ceremonies, rugs, and jewelry.
Sped 2.4 mile sin 10 minutes. THat means in 1 hour 2.4 x6=14.4 miles per hour. 1 hour=60 minutes.
Using trigonometric ratios, the measure of side n to one decimal is 6.6 units.
<h3>How to solve for a side using trigonometric ratios?</h3>
Using the trigonometric principle
SOHCAHTOA,
cos 20 = adjacent / hypotenuse
adjacent side = n
hypotenuse side = 7
Therefore,
cos 20° = n / 7
cross multiply
n = 7 cos 20°
n = 7 × 0.93969262078
n = 6.5778483455
n = 6.6 units
