Answer:
x = 8
Step-by-step explanation:
If a triangle is equilateral, each vertex has an angle that is equal to 60 degrees
As we can see, we have two sets of similar right triangles
The value x faces the right angle and that makes it the hypotenuse
Also, the side measure 4 is the adjacent side to the angle 60
The trigonometric identity that relates the hypotenuse and the adjacent is the cosine
it is the ratio of the adjacent to the hypotenuse
Mathematically;
cos 60 = 4/x
x = 4/cos 60
x = 8
Answer:
a. y÷x=5 , b. y=60 because x is increased by 2 times so y should be increased by 2 times

HOPE IT HELPS:)
97, as it is a supplementary angle, meaning it will add up to 180, so all you have to do is subtract 83 from 180. Would appreciate brainliest!
