The second angle of a triangular kite is four times as large as the first. The third angle is 15 degrees more than the sum of th e other two angles. Find the measure of the second angle.
1 answer:
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15 the three angles make a sum of 180: x+4x +5x+15=180 10x=165 x=16.5 the second angle is 4x=4*16.5=66

Step-by-step explanation:
The rectangle is 1-(-2) = 3 units in the real direction and 4i-(-3i) = 7 units in the imaginary direction. Its area is 3×7 = 21 square units.
Yes.The second factor is the difference of 2 squares, so the second factor alone becomes (x² - 4) = (x + 2) (x - 2)
