Answer:
AB = 5.6 cm
Step-by-step explanation:
To find the length of side AB, which is one of the sides of right angled triangle ABC given above, we would apply the trigonometric ratio formula.
The given angle (θ) = 62°
Length of hypotenuse = BC = 12 cm
Length of adjacent side = AB = ?
We would use the following trigonometric ratio formula:
Cos(θ) = adjacent/hypotenuse
![cos(62) = \frac{AB}{12}](https://tex.z-dn.net/?f=%20cos%2862%29%20%3D%20%5Cfrac%7BAB%7D%7B12%7D%20)
Multiply both sides by 12 to make AB the subject of formula
![cos(62)*12 = \frac{AB}{12}*12](https://tex.z-dn.net/?f=%20cos%2862%29%2A12%20%3D%20%5Cfrac%7BAB%7D%7B12%7D%2A12%20)
![cos(62)*12 = AB](https://tex.z-dn.net/?f=%20cos%2862%29%2A12%20%3D%20AB%20)
![0.4695*12 = AB](https://tex.z-dn.net/?f=%200.4695%2A12%20%3D%20AB%20)
![0.4695*12 = AB](https://tex.z-dn.net/?f=%200.4695%2A12%20%3D%20AB%20)
![5.634 = AB](https://tex.z-dn.net/?f=%205.634%20%3D%20AB%20)
Length of side AB = 5.6 cm (approximated to 1 decimal place)
The length if the garden is 68m, here's my work.
hope this helps, please mark brainliest, I need one more to level up. :)
C. y = 1/2x - 2
<u>Use the slope-intercept form to find the slope and y-intercept</u>
Slope: 1/2
Y-Intercept: -2
40$×20%=
20%×0,01=0,2
40$×0,2=8
so the 40 with 20%interest would be
40$+8=48$
