Answer:

D = 170\º

Step-by-step explanation:

Given

Shape: Pentagon

A = 87\º

B = 125\º

C = 63\º

E = 95\º

Required

Find D

From the sum of angles in a Pentagon; we have that

A + B + C + D + E = 540

Substitute values for A, B, C and E

87\º + 125\º + 63\º + D + 95\º = 540\º

Collect Like Terms

87\º + 125\º + 63\º + 95\º + D = 540\º

370\º + D = 540\º

Collect Like Terms

D = 540\º - 370\º

D = 170\º

<em>Hence, from the list of given options, the correct answer is 170</em>

Determine the common ratio and find the next three terms of the geometric sequence t8, t5, t2
attashe74 [19]
The common ratio of the given geometric sequence is the number that is multiplied to the first term in order to get the second term. Consequently, this is also the number multiplied to the second term to get the third term. This cycle goes on and on until a certain term is acquired. In this item, the common ratio r is,

    r = t⁵/t⁸ = t²/t⁵

The answer, r = t⁻³.

The next three terms are,

    n₄ = (t²)(t⁻³) = t⁻¹
    n₅ = (t⁻¹)(t⁻³) = t⁻⁴
    n₆ = (t⁻⁴)(t⁻³) = t⁻⁷

The answers for the next three terms are as reflected above as n₄, n₅, and n₆, respectively.

Choose the equation that represents the line passing through the point (2, - 5) with a slope of −3.A y = −3x − 13 ,B y = −3x + 1
timurjin [86]

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (2, - 5) into the partial equation

- 5 = - 6 + c ⇒ c = - 5 + 6 = 1

y = - 3x + 1 → D
