Answer:

x = 80°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for x

x = 180° - (50 + 50)° = 180° - 100° = 80°

Answer:

x=80°

Step-by-step explanation:

Triangles always add up to 180°.

As you have 2 angles, you would have to add them together and then take it away from 180° to get your answer.

50+50=100°

180-100=80°

Hope this helps :)

Which answer describes the type of sequence? 200, 40, 8, 1.6, ...

GalinKa [24]

Answer:

Option 1 the given sequence is a geometric.

Step-by-step explanation:

We have been given with the series

$200,40,8,1.6$

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

$d=a_2-a_1$

$d=40-200=-160$ here $a_2=40,a_1=200$

$d=8-40=-32$ here $a_2=8,a_1=40$

We can see the difference is not same

Hence, the given sequence is not arithmetic sequence.

Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

$r=\frac{a_2}{a_1}$

$r=\frac{40}{200}=\frac{1}{5}$ here $a_2=40,a_1=200$

$r=\frac{8}{40}=\frac{1}{5}$ here $a_2=8,a_1=40$

$r=\frac{1.6}{8}=\frac{1}{5}$ here $a_2=1.6,a_1=8$

We can see the ratio is same.

Hence, given sequence is geometric

Therefore, Option 1 is correct given sequence is geometric.

12 plus the product of 2 and some number is equal to the product of 4 and some number minus 8 .

geniusboy [140]

Answer:

The number is 10

Step-by-step explanation:

Let x be the number

product is multiply

12 + (2x) = 4x -8

Subtract 2x from each side

12+2x-2x = 4x-2x-8

12 = 2x-8

Add 8 to each side

12+8 = 2x-8+8

20 = 2x

Divide by 2

20/2 = 2x/2

10 =x

If matrix A has dimensions 3 x 2 and matrix B has dimensions 3 x 2, can matrix A and matrix B be multiplied?

Charra [1.4K]

Matrix A has 3 rows, 2 columns
Matrix B has 3 rows, 2 columns

The number of columns in matrix A (which is 2) does not match up with the number of rows in matrix B (which is 3).

So the matrix multiplication A*B is undefined. We cannot multiply the matrices.
