Area of garden: 18 x 12 = 216 square feet
area for plant: 2 x 2 = 4 square feet
216 / 4 = 54 total plants
Step-by-step explanation:
∠4 = ∠1 & ∠2 = ∠3
360 - 2(98) = ∠2 + ∠3
∠3 = 164/2
∠3 = 82°
Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
In the right triangle ABC
we know that
The triangle ABC is a 
so
Is an isosceles right triangle
The legs are equal
therefore
AC=AB

step 2
Find the length side BC
Applying the Pythagorean Theorem]



step 3
Find the value of y
In the right triangle BCD
----> by SOH (opposite side divided by the hypotenuse)

Remember that

so

step 4
Find the value of z
In the right triangle BCD
----> by CAH (adjacent side divided by the hypotenuse)

Remember that

so
