Answer:

0.866

Step-by-step explanation:

If tan x = 1.731 then sin x =

Given data

tan x = 1.731

x= tan^-1 (1.731)

x= 59.98°

x= 60° approx

Aso

sin x=??

substitute

sin 60°= 0.866

Hence the answer is 0.866

Find the area of this triangle. Round to

DaniilM [7]

Answer:

63.3 square feet

Step-by-step explanation:

Let a = 20 ft, B = 15 ft, c = 9ft

$s=\frac{a+b+c}{2}$

$s=\frac{20+15+9}{2}$

$s=\frac{44}{2}$

$s=22\: ft$

$Area \: of \:\triangle = \sqrt{s(s - a)(s - b)(s - c)} \\ \\ = \sqrt{22(22 - 20)(22 - 15)(22 - 9)} \\ \\= \sqrt{22 \times 2 \times 7 \times 13} \\ \\= \sqrt{44 \times 91} \\ \\ = \sqrt{4,004} \\ \\ = 63.2771681 \\ \\ \approx 63.3 \: {ft}^{2}$

Suppose that the x-intercepts of the graph of y= f(x) are -8 and 1.

Nastasia [14]

Answer:

-4, 5

Step-by-step explanation:

y=f(x)

to find the x intercepts then y must be 0

0=f(x), solutions are x=-8, x=1

when 0=f(x+4), you simply add 4 to each intercept's x coordinate

-8+4=-4

1+4=5

-4, 5

Step-by-step explanation:

<u>Step 1: Define</u>

-1.6 - 2x = 5x + 0.9

<u>Step 2: Solve for </u><em><u>x</u></em>

Add 2x on both sides: -1.6 = 7x + 0.9
Subtract 0.9 on both sides: 2.5 = 7x
Divide 7 on both sides: 0.357143 = x
Rewrite: x = 0.357143
