In the above triangle, if x = , y = 1, and z = 2, then which of the following is equal to tan(60°)?

vesna_86 [32]

Answer: Option A

$tan(60\°) = \sqrt{3}$

Step-by-step explanation:

We know the sides and z. So since it is a straight triangle we use the Pythagorean theorem to pull the length of the x side.

$z ^ 2 = x ^ 2 + y ^ 2\\\\x^2 = z^2 - y^2\\\\x=\sqrt{z^2 - y^2}\\\\x=\sqrt{2^2 - 1^2}\\\\x=\sqrt{4 - 1}\\\\x=\sqrt{3}$

By definition, the tangent of an angle is:

$tan(\theta) = \frac{opposite}{adjacent}$

In this case:

$adjacent = y=1\\\\opposite=x =\sqrt{3}\\\\\theta=60\°$

Then:

$tan(60\°) = \frac{\sqrt{3}}{1}$

$tan(60\°) = \sqrt{3}$

Y and x have a proportional relationship, and y = 7 when x = 2. What is the value of x when y = 21?

RSB [31]

Y and x have a relationship that is directly proportional;
y = 7 when x = 2
when y = 21 and x = ?
y : x
7 : 2
if we multiply 7 wit 3, the answer is 21
3 x 7 : 2 x 3
21 : 6
So, when y = 21, x = 6

Determine whether the two ratios are proportional. 6/36 and 1/6 a) Yes b) No

Xelga [282]

Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)

a skateboard ramp has a slope 2/5.Which is the angle the ramp makes with the ground? A.66 degrees B. Not here C.24 degrees D.22

vovikov84 [41]

We are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.
