Answer:

130°

Step-by-step explanation:

the opposite angle just like in the diagram will always be the same value

then you must know that total angle in triangle must be 180° so the balance angle each 50° bcuz when the length is the same, the angle should be the same too.

to find X , 180-50=130

Xavier and Ava are employees for a company. Xavier is making a salary of $42,700.

MrMuchimi

$62,342 is the salary earned by Ava.

<u>Step-by-step explanation</u>:

<u>step 1</u> :

Xavier's salary = $42,700

<u>step 2</u> :

Ava's salary = 46% higher than Xavier salary.

= 100% of Xavier salary + 46% of Xavier salary

= 146% of Xavier salary

<u>step 3 </u>:

Ava is earning a salary = (146/100) $\times$ 42,700

= 146 $\times$ 427

= 62,342

∴ Ava is earning a salary of $62,342.

Answer:

y = 20

Step-by-step explanation:

$9 - \sqrt{y - 4} = 5$

<h3>i) move 9 to the right-hand side and change its sign</h3>

$- \sqrt{y - 4} = 5 - 9$

<h3>ii) calculate the difference</h3>

$- \sqrt{ y - 4} = - 4$

<h3>iii) change the signs on both sides of the equation</h3>

$\sqrt{y - 4} = 4$

<h3>iv) square both sides of the equation</h3>

$( \sqrt{y - 4} ) {}^{2} = 4 {}^{2}$

$y - 4 = 4 {}^{2}$

$y - 4 = 16$

<h3>v) move -4 to the right-hand side and change its sign</h3>

$y = 16 + 4$

<h3>vi) add the numbers</h3>

$y = 20$

The answer would be 53. This can be found by add 127 twice (xy and uz) and subtracting it from 360. This would give you 106 and you would divide it by 2 for the 2 angles left and get the answer.
