Answer:
doubt
Step-by-step explanation:
................
{-1, 3, 7, 11, 15}
f(x) = 2x − 1, {0, 2, 4, 6, 8}
f(0) = 2*0 − 1 = 0 - 1 = -1
f(2) = 2*2 − 1 = 4 - 1 = 3
f(4) = 2*4 − 1 = 8 - 1 = 7
f(6) = 2*6 − 1= 12 - 1 = 11
f(8) = 2*8 − 1= 16 - 1 = 15
The little square in the top left corner means it is a right angle which equals 90 degrees.
The bottom angle is given as 56.7 degrees.
The three inside angles of a triangle need to equal 180 degrees.
The missing angle = 180 - 90 - 56.7 = 33.3 degrees
