Answer: The answer to number 2 is 30.64177772

This is the Pythagorean theorem and law of sines. Let's do number 2!

Step-by-step explanation:

This is the Pythagorean theorem and law of sines. It's a 90 degree triangle, and they tell you that the other angle is 40 degrees. The total must add up to 180 in total. 90+40=130, 180-130=50. The other angle equals 50 degrees.

The law of sins is sinA/a=sinB/b=sinC/c. sin90/4=sin50/x. x=30.64177772

4(7x - 1) = 3(2x + 1) - 4(x + 6)

mihalych1998 [28]

Answer:

x = -17/26

Step-by-step explanation:

4(7x - 1) = 3(2x + 1) - 4(x + 6)

distribute 4 through the parentheses (do 3 and -4 as well)

28x-4=6x+3-4x-24

collect like terms

28x-4=2x+3-24 --> 28x-4=2x-21

move the variable

28x-2x-4=-21

collect like terms

26x=-21+4 --> 26x=-17

then divide

hope this helps and makes sense! :)
