Answer:
Step-by-step explanation:
If this is in terms of angles, 4x+6 must be equal to 90 since it is half of the angle produced by a line (180°) So solving for 4x+6=90, x=21
Answer:according to the formula of inscribed angle theorem
The answer is 15 degrees
The exterior angle is ∠3 and ∠BAC is 78°
Step-by-step explanation:
An exterior angle is one formed by one side of a triangle and extension of an adjacent side of the triangle.The sum of two non-adjacent interior angles will equal the measure of the exterior angle of the triangle.
In finding the value of ∠BAC first find ∠BCA (180°-113°=67°) ⇒sum of angles formed in a straight line add up to 180°
∠BAC= 180°-(∠ABC +∠BCA)⇒sum of angles in a triangle
∠BAC=180°-(35°+67°)
∠BAC=180°-102°=78°

Hey there! I'm happy to help!
Let's think of this angle being put inside of a unit circle (a circle with a radius of one). This angle is going to stay inside the first quadrant, so all of its trigonometric ratios will be positive.
We are given that the sin of x is 1/5. To get the x by itself, we can just find the inverse sine of both sides to isolate the x.
x=sin(1/5)
x≈ 11.536959
2x≈ 23.073918
Now, we just cosine this value.
cos2x≈ 0.92
