If ∠1 =5x+20 and ∠4 = 14x - 160, find the measure of angle ∠7 & <6

step-by-step explanation:

i am not sure sorry : c

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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!
