The question is pretty much the entire definition of a radian. For an unit circle, its entire circumference is 2π and the entire circle has 2π radians. A quarter circle, or 90°, or π/2 radians, have 1/4th of the circumference. And 2π/4 is π/2. This natural relationship is WHY higher mathematics uses radians for the measurement of angles rather than arbitrary units such as degrees.</span>
Its 73 degrees, hope this helps
Answer:
Step-by-step explanation:
<u>Area of rhombus is:</u>
- A = pq/2, where p and q are diagonals
<u>We have:</u>
<u>The area is:</u>
- A = 18.3*13.8/2 = 126.27 ft²
Correct choice is C

Answer:
LL
Step-by-step explanation:
You are given two congruent legs: BC≅BC and AC≅DC. The fact that it is a right triangle lets you invoke the LL theorem of congruence for right triangles. (This is a special case of the SAS theorem, where the A is 90°.)
