Answer:

P = 76 feet, A =338 square feet

Step-by-step explanation:

You got perimeter right, so I assume you don't need explaining.

The area for the rectangle is 270 square feet since 18 x 15 = 270. The area of the triangle is 68 since 17 x 8 is 136, and dividing by 2 gives 68.

Now add 270 and 68, which gives 338 square feet.

Quadrilateral ABCD is inscribed in a circle. Angle B measures 19°. What is the measure of angle D?
kherson [118]

Answer:

D = 161^o

Step-by-step explanation:

Given

\angle B = 19^o

Required

Find D

The label of the quadrilateral are not clear. However, a more complete question illustrates that B and D are opposite sides.

To solve for D, we make use of:

B + D = 180^o ---- opposite sides of a cyclic \\ quadrilateral

Make D the subject

D = 180^o -B

D = 180^o -19^o

D = 161^o

Work out the nth of this sequence:
Gekata [30.6K]

Answer:

a_n = -11 +3(n -1)

Explanation:

The nth term of an arithmetic sequence is explicitly defined as a_n = a_1 +d(n -1) where a_1 is the first term of the sequence and d is the the common difference.

From the given first five terms of the sequence we can see that the first term is 11 so a_1 = 11.

The common difference, d, can be calculated by a_n - a_{n -1} so we'll find the common difference of the given sequence by letting n = 2

d = a_2 - a_{2 -1} \\d = a_2 -a_{1} \\d = -8 -(-11) \\ d = -8 +11 \\ d = 3.

Now let's plug everything we know.

a_1 = -11

d = 3

a_n = -11 +3(n -1)
