Answer:
x = 15√3
y = 30
Step-by-step explanation:
In a 30°-60°-90° "special" triangle, the ratios of side lengths are ...
1 : √3 : 2
Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.
1 : √3 : 2 = 15 : x : y = 15 : 15√3 : 30
x = 15√3
y = 30
Answer:
A. 60°
Step-by-step explanation:
From the diagram, in triangle ABC,
AB=BC=CA=15 units.
This means triangle ABC is an equilateral triangle.
All angles in equilateral triangle are congruent. The sum of all interior angles in triangle is always 180°, so one angle of equilateral triangle is equal to 60°. Thus,
∠A=∠B=∠C=60°
