Smaller angle = 41°

Larger angle = 139°

Step-by-step explanation:

(7x - 1) + (2x + 1) = 180

7x + 2x - 1 + 1 = 180

9x = 180

x = 20

The measure of the smaller angle is

2x + 1

= 2(20) + 1

= 40 + 1

= 41°

The measure of the larger angle is

7x - 1

= 7(20) - 1

= 140 - 1

= 139°

Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10?

PSYCHO15rus [73]

Answer: The sequence generated is 10, 8, 6, 4, 2, ...

This sequence is arithmetic with starting term 10 and common difference -2. This means we add -2 to each term to get the next one (same as subtracting 2 from each term). This common difference is directly connected to the -2 from the recursive rule f(n+1) = f(n)-2

Whatever the nth term f(n) is, we subtract off 2 to get f(n)-2 to get the f(n+1) term, which is right after the nth term.

If 2/x+ 3/y =13 and 5/x- 4/y = -2, then x+y equals

creativ13 [48]

Answer:

$x + y = \frac{5}{6}$

Step-by-step explanation:

Let:

$u = \frac{1}{x} \\ v = \frac{1}{y}$

This allows us to manipulate the equations like we normally would.

$2u + 3v = 13 \\ 5u - 4v = - 2 \\ \\ + 8u + 12v = 52 \\ + 15u - 12v = - 6 \\ 23u = 46 \\ u = 2 \\ \\ 2(2) + 3v = 13 \\ 4 + 3v = 13 \\ 3v = 9 \\ v = 3$

Then, we return the values where they belong.

$u = \frac{1}{x} \\ 2 = \frac{1}{x} \\ x = \frac{1}{2} \\ \\ v = \frac{1}{y} \\ 3 = \frac{1}{y} \\ y = \frac{1}{3}$

Finally, we add:

$\frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}$

Two carbon atoms and 1 oxygen atom contain 20 protons. One carbon atom and 2 oxygen atoms contain 22 protons. How many protons a

Alisiya [41]

Answer:

Carbon has 6 protons while oxygen has 8 protons.

Step-by-step explanation:

Let x be the number of protons in carbon and y be the number of protons is oxygen.

ATQ: 2x+y=20 and x+2y=22. Solving it, we will get x=6 and y=8

Triangle ABC is similar to triangle WYZ.

Inga [223]

9514 1404 393

Answer:

False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

sin(B) > sin(Y) . . . . FALSE

sin(B) = sin(Y) . . . . true
