X = 90 degreees, so you take 47 and 90 add them together and you get 137 degrees. you need 180 to make a triangle, so you subtract 137 from 180. the answer for y is 43 degrees. hope that helps

PLZ ANSWER. UR THE BEST IF U DO. I’LL GIVE BRAINLIEST

You basically can solve for hypothetical sides of this triangle using sohcahtoa backwards. In the first column, it says that adjacent/hypotenuse = .97. We can come up with two values that satisfy this equation. For example, the adjacent side can be .97 and the hypotenuse can be 1. These values don't matter as long as adjacent/hypotenuse is .97.

The second column tells us that opposite/hypotenuse = .26. At this point, we already have a hypothetical hypotenuse with a length of 1, so we can plug that in and find that the opposite side of C is .26.

Now that we have a hypothetical triangle with sides .97, .26, and 1, you can use these values as well as sohcahtoa to solve for the rest with respect to angle A. Keep in mind that the line AB is .26 and that the line BC is .97.

As a reward for being name employee of the year Janice will receive a 3.5 pay raise . If Janice new salary is 45,000 how much wa

satela [25.4K]

Answer:

Salary before pay raise = 43,478.26 (approx)

Step-by-step explanation:

Given that:

Janice new salary = 45,000

Pay raise = 3.5% = 0.035

Let the previous pay be x

Now according to given conditions:

0.035* x = 45,000 - x

Adding x on both sides we get:

0.035 x + x = 45,000 - x + x

1.035x = 45,000

Dividing both sides by 1.035 we get:

1.035/1.035 x = 45,000/1.035

x = 43,478.26

So, the salary before pay raise was 43,478 approx

proof:

Raise in salart = 3.5% of 43,478.26 = 1,521.74

New salary = old salary + raise in salary

New salary = 43,478.26 + 1,521.74

New salary = 45,000

Hence proved.

I hope it will help you!

The lengths of the sides of a triangle are 3, 4, 5. Can the triangle be a right triangle?

attashe74 [19]

Yes, this is a typical pythagorean triad.

Since the theorem is: $c^{2} = a^{2} + b^{2}$
And by inspection, $5^{2}$ would be the hypotenuse,
$5^{2} = 3^{2} + 4^{2}$
25 = 9 + 16
RHS = 9 + 16 = 25 = LHS
Therefore, we have proved that the values fit into pythagoras' theorem, which means that the triangle is a right triangle (that is the central idea of this theorem).
