Answer:
x = -5.25 or 21/4
Step-by-step explanation:
When break the bracket out, if there is a minus sign in front of the bracket, when we break it out, the sign inside the bracket would become positive:
67 = 18 - (8x - 7)
67 = 18 - 8x - (-7)
67 = 18 - 8x + 7
67 = 18 + 7 - 8x
67 = 25 - 8x or rewrite for easier look: 25 - 8x = 67
25 - 8x = 67
8x = 25 - 67
8x = -42
Divide both side by 8, we got:
x = -42 / 8
x = -5.25 or 21/4
Hope this helped :3
An isosceles right triangle is composed of a right angle and two congruent acute angles. In this case, 90 + 2x = 180 where x is the acute angle. x is equal to 45 degrees. Using sine law, 8/sin 90 = y / sin 45 where y is the leg of the triangle. the leg's length is equal to 4 sqrt 2.
