Answer:
6.2
Step-by-step explanation:
*Cross multiply*
10.3(sin(37)) = x(sin(90)) *Divide by sin(90) to isolate x*
*Solve*
x = 6.19 ≈ 6.2
now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)
now combine "like terms" (-58) with (-58) and 2h with (-h)
now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.
now add the two terms together
the final result is 157
