Answer:

$x+8$

Step-by-step explanation:

we know that

The phrase " the sum of x and 8" is equivalent to adds the number x and the number 8 or sum the number x plus the number 8

Please help! Geometry.

These are right triangles that will use either sin, cos, or tan, depending upon what you have to work with in regards to the reference angle. The first one has a reference angle of 51 with y being the side opposite it and 12 being the hypotenuse. The sin identity uses the side opposite over the hypotenuse as its formula:
$sin(51)= \frac{y}{12}$
and 12 sin(51) = y and y = 9.325
The second one has the reference angle as the unknown. You could use any of the identities here because you have all the sides of the triangle, but I will use sin again:
$sin \beta = \frac{12}{13}$
and $sin \beta =.9230769$
and $sin ^{-1}(.9230769)=67.38$
The next one has a referece angle of 13 with 24 being the side adjacent to it and the unknown being the side across from it. You will use the tangent identity here:
$tan(13)= \frac{x}{24}$
and 24 tan(13) = x so x = 5.540
The last one has a reference angle of 20 with the hypotenuse as the unknown x, and the side across from it as 10. Use the sin identity again:
$sin(20)= \frac{10}{x}$ and
$x sin(20)=10$ and
$x= \frac{10}{sin(20)}$ with x = 29.238
Everything is in regards to the reference angle; you HAVE to be able to identify the reference angle and then how the given sides are related to it.

Lara said that point D has a value of 38. is her statement reasonable? Explain your answer.

Ratling [72]

Point D is located between 35 and 40 so the possible answers are 36, 37, 38, and 39.

Point D is closer to 40 than 35, so we narrow down the option to 38 or 39.

39 would have been really close to 40, so Lara's statement is reasonable to say 38 is point D.

Simplify 3a^2b^3c^5 __________________ 8x^4y^3z

Jobisdone [24]

We have to rewrite the expression so that it has no denominator.
For example:
1 / x = x^(-1)
1/8 = 8^(-1); 1/x^(4) = x^(-4); 1/y^(3) = y^(-3); 1/z = z^(-1).
$\frac{3a ^{2} b ^{3}c ^{5} }{8 x^{4}y ^{3}z }= \\ =3 a^{2}b ^{3}c^{5}8^{-1}x ^{-4}y^{-3}z^{-1}$
