Step-by-step explanation:
∆PQR similar to ∆ JKL
JK/KL= PQ/QR
6/12=3/QR
QR=3×2= 6
therefore, tan(R) = PQ/QR = 3/6=1/2
and, tan(J) = KL/JK =12/6=2
tan(J)=4.tan(R)
option D
If the probability of flipping heads is 0.70, the probability of flipping tails is 0.30.
To find probability, you multiply the probability of each factor together:
P = 0.7 * 0.3
P = 0.21 <em>or</em><em> </em>21%
