Answer:
A.) 40°
Step-by-step explanation:
A triangle is equal to 180°
Angle X and Y has the same angle, so both have 70°.
So:
70° × 2= 140°
To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.
So:
180° - 140°= 40°
Answer= 40°

I guess by if you are at the top and you don't want to go down the steepest line you look a the diameter of each area where the line is and also look down from the top you shoe be able to notice the slight contrast
The value of cos(L) in the triangle is Five-thirteenths
<h3>What are right triangles?</h3>
Right triangles are triangles whose one of its angle has a measure of 90 degrees
<h3>How to determine the value of cos(L)?</h3>
The value of a cosine function is calculated as:
cos(L) = Adjacent/Hypotenuse
The hypotenuse is calculated as
Hypotenuse^2 = Opposite^2 + Adjacent^2
So, we have:
Hypotenuse^2 = 12^2 + 5^2
Evaluate
Hypotenuse^2 = 169
Take the square root of both sides
Hypotenuse = 13
So, we have
Adjacent = 5
Hypotenuse = 13
Recall that
cos(L) = Adjacent/Hypotenuse
This gives
cos(L) = 5/13
Hence, the value of cos(L) in the triangle is Five-thirteenths
