Answer:

C = 75°

Step-by-step explanation:

The interior angles of a triangle will <u>always</u> add up to 180°, so all we have to do is find the missing variable.  

To do this, we first add up the two angles we <em>do</em> know.

—> 65 + 40 = 105      

Now that we have the total of the other two angles, simply subtract 105 from 180.

—> 180 - 105 = 75

We now have our answer!

In ΔWXY, the measure of ∠Y=90°, XW = 85, WY = 84, and YX = 13. What is the value of the cosine of ∠W to the nearest hundredth?
IgorLugansk [536]

Answer: 0.99

Step-by-step explanation:

SOH CAH TOA

CAH: cosine = adjacent/hypotenuse

Cosine of angle w = 84/85 = 0.98823 ≈ 0.99

Angle Y is 90 degrees, meaning it's a right triangle. Therefore angle W is the top/tip of a triangle, while X is the angle next to Y. If you plug in the information afterwards and follow the trigonometry rule (SOH CAH TOA) you will find your answer.

RoseWind [281]

Answer:

No, the blinds will not fit inside a 45-inch space.

Step-by-step explanation:

No, the blinds will not fit inside a 45-inch space, because the blinds are too large.

To check;

140 cm = 56 inches

140 / 2.5 = 56

&

45 inches = 112.5 cm

45 x 2.5 = 112.5

Hope this helps!
