Answer:
34
Step-by-step explanation:
Since this an isosceles triangle we can say the length of AB = AC
2x - 1 = x + 7
2x - x = 7 + 1
x = 8
The perimeter is calculated by adding all side lengths
2x - 1 + x + 7 + x - 4 = Area add like terms
4x + 2 = Area replace x with the value we found
4*8+2 = 34 units square
1000 candy bars ... $350
1 candy bar ... $x = ?
If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:
1000 * x = 350 * 1
1000 * x = 350 /1000
x = 350 / 1000
x = $0.35
Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
