Y= x-5 is equivelent to the equation
Answer:
m3 is 60 degrees
Step-by-step explanation:
Angles 1 & 3 are complementary angles. What that means is that the two angles equal 180 degrees. We already have 120 degrees with m1, so subtract that from 180 for 60 degrees.
Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
<u>w = -7/2</u>
