Solve the value of a in the right triangle above with c=39 and A=40degree
1. Solve the value of a in the right triangle above with c=39 and A=40degree
Answer:
29.88
Step-by-step explanation:
In a right triangle, side "c" will always be the hypotenuse and is always opposite the right angle.
Side A will always be opposite Angle A.
To find Side A, we should use one of the trigonometric functions, and we will use cosine since cos θ = [tex]\frac{opposite}{hypotenuse}[/tex]. (θ is the angle that we will use)
Plugging in the information that we know:
[tex]cos (40) = \frac{a}{39}[/tex] (We are looking for side "a")
[tex]39 cos(40) = a[/tex] (multiply both sides by 39 to isolate "a")
[tex]29.88 = a[/tex] (rounded off two decimal places)

4. the winds blow toward 40degree with avelocity of 50km/h.what is the vertical component of the winds velocity
Answer:
The vertical component of the wind's velocity is 32.14 km/h
Explanation:
Here, we are to solve only for the vertical component of the wind's velocity. To do this, we get the product of the sine of the given angle and the velocity of the wind.
For the formula, we use:
Vy = V sinθ
where
Vy is the vertical velocity of the wind, unit is in km/h
V is the velocity of the wind
θ is the given angle
For the given information
θ = 40°
V = 50 km/h
Vy = ?
Solving the problem
Let us use the given formula to solve for the vertical component of the wind, we have:
Vy = V sinθ
Then substitute the given information, we have:
Vy = (50 km/h) sin 40°
Vy = 32.14 km/h
Therefore, the vertical component of the wind is 32.14 km/h

6. A ray of light is reflected from a plane mirror. The angle of incidence is 20degrees. The angle between the incident and the reflected ray is _______ a. 10degrees b. 30degrees c. 20degrees d. 40degrees
Explanation:
Since angle of incidence is equal to the angle of reflection, we can also say that angle between the incident ray and reflected ray is twice the angle of reflection or incidence.
Thus, as per above case the angle between the incident and the reflected ray is
= (20*2)
= 40 degrees.
Therefore, d. 40 degrees is the angle between the incident and the reflected ray.
Hello Mam.
Here is the answer---
→→→→→→→→→→→→→
Given, the angle of the incidence(i) = 20°
As per as the second law of Reflection, the angle of incidence is always equals to the angle of Reflection.
Thus, angle of Reflection(r) = 20°
The angle between the incident ray and the reflected ray = i + r
= 20° + 20°
= 40°
Thus the option(d) i.e., 40° is the correct answer.

Have a nice day.

7. Aswang, Real or Fantasy?Babylyn E. CalcetasNo. of Words: 198I grew up living with my Lola in her ancestral house in Atimonan, Quezon, October 1984, two daysbefore All Souls Day somebody knocked at the door in the shadowy night. “Lola Lilang, you ho! Lola Lilang!"I opened the door and saw a man in his rain cloth chilling like a baby in his 40-degree fever. "Hija, please tellyour Lola that my wife is about to deliver our second baby, and I need her to come with me." My Lola thenwas a well-known “manghihilot" in town and a midwife's assistant during her younger years.While they were passing the Emilio Aguinaldo street my grandmother told me that they saw a half-bodied creature "manananggal" hanging on the branches of the big and old guava tree. The said tree wasadjacent to the 18 hundred-year old house they called Marevic. From then on, I was convinced that there isreally "ASWANG" in Atimonan,My belief of creepy creatures became intense when Rated-K of Ms. Korina Sanchez, featured thealleged white lady that usually appeared along Atimonan ZigZag Road.

13.What is 25 degrees lower than the boiling point of water?
100 degrees celsius is the boiling point of the water.
if minus with 25 the result is 85, so 85 degrees celcius
14.6 above the normal body temperature.
37 degrees Celsius is the normal body temperature if added with 6 degrees celcius the result is 43 degrees celcius.
15.Ana's temperature this moming is 37.8. After 3 hours her temperature was 40.7. How many?
40.7-37.8=29 so its 29 degrees
