no solution
Step-by-step explanation:
2x-5=8x+7-6x
2x-5=2x+7
-5=7
Not true so no solution
Possible lengths of the shadow are 6√3 in and 2√3 in
Step-by-step explanation:
- Step 1: The stick is placed in the ground and so makes a right angle with the ground. To find the shadow, use the trigonometric ratios using the angles 30° and 60° along with opposite side of length 6 in.
- Step 2: Find the length of the shadow, which is the length of the adjacent side.
tan A = opposite side/adjacent side
For A = 30° ⇒ tan 30 = 6/adj side
⇒ Adjacent side = 6/tan 30 = 6 ÷ 1/√3 = 6√3 in
For A = 60° ⇒ tan 60 = 6/adj side
⇒ Adjacent side = 6/tan 60 = 6/√3 = 2√3 in
I'd say centimeters, if that's what you're looking for. Maybe 1-2 cm.
So u basically round 8 which is 10 and then add the 1 from 10 to 9 which is 10 and add the 1 to 3 which is 4
Answer:
The height of the trapezoid is 4ft
Step-by-step explanation:
First of all, to solve this problem we need to use the area formula of a trapezoid:
A = area = 20ft²
b1 = base 1
b2 = b2
h = height
b1 + b2 = 10ft
A = ½ (b1+b2) * h
we replace with the known values
20ft² = ½ (10ft) * h
20ft² = 5ft * h
20ft² / 5ft = h
4ft = h
The height of the trapezoid is 4ft
