Answer:

<h2>7.14 ft </h2><h2>I hope it helps :)</h2>

Step-by-step explanation:

$Hypotenuse = 10\\Opposite = 7\\Adjacent = x\\ \\Using Pythagoras theorem ;\\Hyp^{2} =opp^{2} +adj^{2} \\10^{2} = 7^{2} +x^{2} \\100 = 49+x^{2} \\x^{2} =100-49\\x^{2} =51\\\sqrt{x^{2} } =\sqrt{51} x = 7.14 ft$

a gardenner is designing a new garden in the shape of a trapezoing she wants the short base to be twice the height and loger bas

taurus [48]

Answer:

Height = 5 ft

Short base = 10 ft

Long base = 14 ft

Step-by-step explanation:

Let h = height, a = short base, b = long base.

From the question,

a = 2h

b = a + 4 = 2h + 4

The area of the trapezoid is given by $\frac{1}{2}(a+b)h$ . Thus,

$60 = \frac{1}{2}(2h + 2h + 4)h$

$60 = \frac{(4h + 4)h }{2}$

$60 = \frac{4h(h + 1)}{2}$

$60 = 2h(h + 1)$

$30 = h(h + 1)$

$0 = h^2 + h - 30$

$0 = (h+6)(h-5)$

$h-5 = 0$ or $h+6 = 0$

$h= 5$ or $h = -6$

We discard the negative value of h since it is a measurement and cannot be negative.

$h= 5$

$a= 2h=2\times5=10$

$b= a+4=10+4=14$

Line AB has endpoints A(3,4) and B(-2,8). What is AB to the nearest tenth

Nadya [2.5K]

Answer:

6.4

Step-by-step explanation:

To find the distance you have to do this formula.

$\sqrt{(x2 -x1)^{2}+(y2-y1)^{2}} \\\sqrt{(-2 -3)^{2} + (8-4)^{2}\\} \\\sqrt{(-5)^{2} + (4)^{2}} \\\sqrt{25 + 16} \\\sqrt{41} \\ \\\sqrt{41} = 6.40312\\6.4$

6.4 is the answer rounded to the nearest tenth.

Hope this helps!!
