We know that
in a right triangle
cos θ=adjacent side angle <span>θ/hypotenuse
in this problem

</span>adjacent side angle θ=38 in
hypotenuse=40 in

cos θ=38/40
θ=arc cos (38/40)-------> 18.19°-------> 18°

the answer is
18 degrees

I needs help with it please ​
BARSIC [14]

Answer:

d.  ΔMNO

Step-by-step explanation:

In geometry, two figures are <u>congruent</u> if they are the <u>same shape and size</u> (they can also be a mirror image of each other).  If they are the same shape but a <u>different size</u> (e,g, one is an enlargement or reduction of the other), then they are <u>similar</u>.

All the given triangles have the same interior angles, so we need to find a triangle with the same side lengths as ΔABC.  

The only triangle that has the same side length as ΔABC is ΔMNO:
they both have bases of 8cm.

Therefore, ΔMNO is congruent to ΔABC.

Suppose you have 13 tubes of paint. How many distinct color groupings can you make with your paint?
anzhelika [568]

Answer:

32767 distinct color grouping

Step-by-step explanation:

Given data:

Total tube is 13

for distinct color, group can be 1,2,3,4,.... 15

For total number of ways we have following relation

^nC_0 +^nC_1 +^nC_2 + .......^nC_n = 2^n

here n = 13 so we have

^15C_0 +^15C_1 +^15C_2 + .......^15C_{15} = 2^15

for at least one

= 2^{15} - 1

= 32768 -1

= 32767 distinct color grouping

Guthrie made the input-output table shown below.
Inga [223]

9514 1404 393

Answer:

  C  3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

  m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

  C  3x +1 = y

__

If you check this against the table entries, you find it fits.

  3(1) +1 = 4

  3(2) +1 = 7

and so on.
