Answer:
55,98,27
Step-by-step explanation:
To solve for the angles we must first find y with this equation
3y+5+2y-7=153
We can simplify this
5y-2=153
153+2=155
155/5=31
y=31
We now know y and can plug it into the angles
<A=2y-7
2(31)-7
62-7
55
<A=55
<B=3y+5
3(31)+5
93+5
98
<B=98
Now time for the last angle
Since angle BCA and DCB are next to each other they add up to 180
153+x=180
180-153=27
x=27
<BCA=27
<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.
Formula for calculating noon sun angle is:
Noon_sun_angle = 90° - Zenith angle
We have complementary angles so we need to substract zenith angle from 90°.
The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.
New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°
Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°
Answer:
The triangle has two sides that are equivalent and the angle where the two meet are also equivalent.
In other words, two sides and the angle between them are congruent.
