Answer:
x = 43 degrees; 2x = 86 degrees; x+ 8 = 51
Step-by-step explanation:
x + 2x + x + 8 = 180
4x + 8 = 180
- 8 -8
4x = 172 (divide both sides by 4)
x = 43
Notice the picture below
due to equal sides on each scalene triangle, the angle bisector cuts the horizontal in half
thus, use the pythagorean theorem to get the "b" or opposite side
also notice, that "b" is also the altitude or height "h"
what's the area? well, area of a triangle is 1/2 bh
get the area of each triangle and sum them up, that's the area of the kite
Answer:
3pi/4
Step-by-step explanation:
well we know that sin of pi/2 we just need to solve for 2x-pi = pi/2
so that means that 2x must be 3pi/2 and x is 3pi/4
