Answer:
515.
Step-by-step explanation:
40 x 12 = 480
480 + 35 =515
Answer:
tanG = 2
tanH =
Step-by-step explanation:
The function tangent is the opposite side divided by the adjacent one(SohCahToa).
Relative to angle G, the side with measure 2 is opposite while the wide with measure 1 is adjacent. From this we can set up an equation and substitute:
tan(m<G) =
tan(m<G) =
The same can be done for <H. The opposite side is 1 while the adjacent is 2:
tan(m<H) =
tan(m<H) =
The two angles form a a straight line which is equal to 180 degrees:
Make an equation:
57 + (x +23) = 180
Simplify:
x + 80 = 180
Subtract 80 from both sides:
x = 100
The answer is A because completing the square gives a minimum of 2,-9 and factorising gives roots of 5 and -1 :)
