find the two angle measures from the diagram 3x+10 3x-28 there's 3 answer's 71,71 109 ,109 109,71 last question brainiest u will

andriy [413]

Answer:

Step-by-step explanation:

3x + 10 + 3x - 28 = 180

6x = 180 - 10 + 28

x = 198/6

x = 33

substitute the value of x = 33 back into the equation to solve for each angle

= 3x + 10

= 3(33) + 10

= 109

= 3x - 28

= 3(33) - 28

= 71

Your friend asks you to help cut grass this summer and will pay you 2 pennies for the first job. You agree to help if he doubles

Harrizon [31]

Let $p_n$ be the amount of pennies received for lawn $n$ . Then, $p_1 = 2$ and $p_{n+1} = 2p_n$ .

We claim by induction that $p_n = 2^n$ . The base case is trivial ( $p_1 = 2^1 = 2$ is given). Then, we complete the inductive step. If $p^n=2^n$ , we have:

$p_{n+1} = 2 \cdot 2^n = 2^{n+1}$

This completes the proof.

Thus, $p_{15} = 2^{15} = 32768 = $327.68$ .
