The measure of ac = 7, mbac = 80°, mabc = 50°, the measure of nm = 7, mlnm = 80°, and mnlm = 50°. do the measurements indicate that abc nlm?

*I need more detail* but if I guessed than the question is asking if the are equal  triangles.

Δabc=Δnlm

Step-by-step explanation:

Draw out both triangles and label them as described in the question. If one angle of the triangles are 80° and 50° than the other angle has to be measured as 50° because all the angles have to add up to 180°. And both triangles are said to have angles 80° and 50°. The length of ac and ab are equivalent because it is an isosceles triangle and same goes for Δnlm.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
