BrainiestI WILL GIVE BRAINLIEST look at the right angled triangle abc

marissa [1.9K]

Answer:

x = 90°

y = 40°

z = 40°

Explanation (Concepts) :

A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

Workouts:

z + 90° + 50° = 180°

z = 180° - 90° - 50°

z = 40°

=================

x + 90° = 180°

x = 180° - 90°

x = 90°

==================

50° + 90° + y = 180°

y = 180° - 90° - 50°

y = 40°

n 1 2 3 4 5 6

f(n) 1033 932 831 730 629 528

First term (a₁): 1033 Common difference (d): -101

Explicit rule: $a_{n} = 1134 - 101n$ Recursive rule: $a_{n} = a_{n-1} - 101$

$a_{n} = a_{1} + d(n - 1)$

$a_{n} = 1033 - 101(n - 1)$

$a_{n} = 1033 - 101n + 101$

$a_{n} = 1134 - 101n$

Explicit rule: $a_{n} = -49 + 10n$ Recursive rule: $a_{n} = a_{n-1} + 10$

$a_{n} = a_{1} + d(n - 1)$

$a_{n} = -39 + 10(n - 1)$

$a_{n} = -39 + 10n - 10$

Explicit rule: $a_{n} = 5 - 1.25n$ Recursive rule: $a_{n} = a_{n-1} - 1.25$

$a_{n} = a_{1} + d(n - 1)$

$a_{n} = 3.75 - 1.25(n - 1)$

$a_{n} = 3.75 - 1.25n + 1.25$

NEED HELP FAST 30nPOINTS FOR BRAINLIEST √5x + √6 = √9

vodka [1.7K]

$\sqrt{5x}$ + √6 = √9

The first step is to get $\sqrt{5x}$ by itself. We can do this by subtracting $\sqrt{6}$ from each side, and simplifying $\sqrt{9}$

$\sqrt{5x}$ = 3 - $\sqrt{6}$

Now we square both sides

5x = (3 - $\sqrt{6}$ )²

Using the formula (a - b)² = a² -2ab + b², (3 - $\sqrt{6}$ )² = 15 - 6 $\sqrt{6}$

5x = 15 - 6 $\sqrt{6}$

x = $\frac{15 - 6\sqrt{6}}{5}$
