Barbara is building a wooden cabin. the cabin is 42 meters wide. she obtained a bunch of
27 meters long wooden beams for the roof of the cabin.
naturally, she wants to place the roof beams in such an angle that each pair of opposite beams would meet exactly in the middle.
what is the angle of elevation, in degrees, of the roof beams?
round your final answer to the nearest tenth.

1

step-by-step explanation:

it's the only multiple of both and the least

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
