Find logarithm of both sides
log (3^x) = log 8
xlog3 = log8
x = log8/log3
x = 1.893
Answer:
z=3
Step-by-step explanation:
→32+76+24z=180[Sum of all sides of a triangle]
→108+24z=180
→24z=180-108
→z=72/24
→z=3
Question is Incomplete;Complete question is given below;
Jerry sold 7/20 of the total number of tickets that were sold for the spring band concert. What percent of the total number of tickets did jerry sell.

Hence Jerry sold 35 % of the total tickets.
Seca(1-sina)(seca+tana)=1
Left hand side
=(1-sina) (seca +tana) / cosa
=seca +tana - sinaseca - sinatan / cosa
=seca + tana -tana -(sin^2a/cosa) / cosa
=(1/cosa - sin^2a/cosa) / cosa
= (1-sin^2a / cosa) / cosa
= (1-sin^2a)/ (cos^2a)
=1 (verified)
