It seems you will have to use a LOT of trigonometric calculations.
Line AC = 26
Line AD = 13 = Line DC = 13
Line BF = 13

Angle ABC = Angle GBF = Angle FBH = 55 degrees each

cosine 40 = 13 (Line AD) / Line AE
Line AE = 13 / 0.76604 = 16.97

tangent 40 = ED / AD = ED / 13
Line ED = 0.8391 * 13 = 10.908

Line DC =13

Angle ABC = 55 degrees
tangent(55) = 26 / AB
AB = 26 / 1.4281 = 18.206

Well, that's about half the calculations.
(As I said it's a lot of work).

Colin found 22 more mushrooms than Sophie did while they were out picking them in the forest. On the way home, Sophie asked Coli

Vinvika [58]

Answer:

11 mushrooms

Step-by-step explanation:

If Colin has 22 more mushrooms than Sophie, then Sofie has 22 less. Half of 22 is 11, so Colin should have 11 less, and Sophie should have 11 more. If you plug a random value into Sophie's mushrooms, this should still work. For example, if Sophie has 2 mushrooms and Colin has 24, they'll both have 13.

Travka [436]

Answer:

x + 3 = 0.

Step-by-step explanation:

One would be:

x + 3 = 0 Subtract 3 from both sides:

x + 3 - 3 = 0 - 3

x = -3

-6d=-42 can you help me solve please

eduard

Given the equation :

$-6d=-42$

So, to find d , divide both sides by ( -6 )

So,

$\begin{gathered} \frac{-6d}{-6}=\frac{-42}{-6} \\ \\ d=7 \end{gathered}$

Note: when we divide two negative numbers, the result will be a positive number

Gemiola [76]

Answer:

Step-by-step explanation:

$x^2=20; \ => \ \left[\begin{array}{ccc}x=\sqrt{20} \\x=-\sqrt{20} \end{array} \ => \ \left[\begin{array}{ccc}x=2\sqrt{5} \\x=-2 \sqrt{5} \end{array}$
