Answer:
60°
Step-by-step explanation:
tan 60 = sin 60 / cos 60
= [(root 3) / 2] ÷ [1/2]
= root 3
[sin 60 = (root 3) / 2 ; cos 60 = 1 / 2 ]
Calculate the lengths of the sides of the triangle:
The triangle has three different sides, so it's a scalene triangle.
Now if c is the longest side of the triangle, and a and b are the shorter sides, then:
- if , the triangle is right
- if , the triangle is acute
- if , the triangle is obtuse
The longest side is 5.
The square of the longest side is equal to the sum of the squares of the shorter sides, so it's a right triangle.
The triangle is a right scalene triangle.
When x = 8 y = 15
The way to figure this out is to subtract 12 by 5. That’s 7 so there’s a difference of 7 between both of the numbers.
Hope this helped!
