Do you see the right triangle in the picture ?

The TANGENT of angle-x is 10m/17.3m. Do the division, find that number, then use your calculator or search online to find the angle that has that number for its tangent.

I get roughly 30 degrees, but you should check me.

We know that :

Tan\theta = \frac{Opposite\;Side}{Adjacent\;Side}

From the Figure :

Tanx = \frac{Height\;of\;the\;Tree}{Shadow\;of\;the\;Tree}

Given : Height of the Tree = 10 m

            Length of its Shadow = 17.3 m

⇒ Tanx = \frac{10}{17.3} = 0.578

⇒ x = Tan^-^1(0.578)

⇒ x° = 30°

Solve ax + b = cx + d for x.
romanna [79]

Answer: X = (d-b) / (a-c)

This way this worded is weird but I think I got it

Step-by-step explanation:

Subtract B from both sides

ax = cx +d -b

Then subtract CX from both sides

ax -cx =d-b

Distributive Property

x(a-c) =d-b

Divide both sides by a-c

X = (d-b) / (a-c)

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have m = 3 and b = -3. Substitute:

<h3>y = 3x - 3</h3>

Salsk061 [2.6K]

Answer:

.01%*

Step-by-step explanation:

Individually, they both have a rate of failure of 1%.

.01 x .01 = .0001

Therefore they have a combined probability of failure of .01%

*Disclaimer!!

I am not the best at this area in math so I would still reference against someone else's answer, but this is my best effort :)
