Answer:
65.5 degrees
Step-by-step explanation:
Triangles add up to 180 degrees. So, the last value has to make the rest add up to 180.
Let x be the unknown degree.
61 + 53.5 + x = 180.
You cancel out the 61 and the 53.3 by subtraction, making you get
x = 65.5

200 -( 5(15) + 2(12) + 70)
200 - (75 + 24 + 70)
200 - 169 = 31
1a. Range of the Function: {3, 5, 7, 9}
D. {3, 5, 7 9}
1b. f(x) = 4 when x = 12
f(x) = 20 when x = 60
B. 20
1c. f(x) = |4x| + 2
f(x) = |4(0)| + 2
f(x) = |0| + 2
f(x) = 0 + 2
f(x) = 2
D. (x, f(x)) = (0, 2)
