Answer:
The value of x is 65° and the value of y is 155°
Step-by-step explanation:
Refer the attached figure
In triangle ABC
<u>Angle sum property of triangle</u> : Sum of all angles of triangle is 180°
So, 25°+90°+x=180°
115°+x=180°
x=180°-115°
x=65°
<u>Exterior angle property </u>: An exterior angle of a triangle is equal to the sum of the two opposite interior angles
So, 90°+x=y
So, 90°+65°=y
155°=y
Hence The value of x is 65° and the value of y is 155°
Answer:
Step-by-step explanation:
Below is the pic of how this would be set up in order to determine what it is you are looking for. The angle is set in QI, and since csc A is the reciprocal of sin, the ratio is hypotenuse over side opposite. Solve for the missing side using Pythagorean's Theorem:
and
1369 = 144 + b² and
1225 = b² so
b = 35
The sec ratio is the reciprocal of cos, so if cos is adjacent over hypotenuse, the sec is hypotenuse over adjacent, which is 37/35
Answer:
3/4
Step-by-step explanation:
Because the total homework would be 25/25
15/20 can be reduced to 3/4
