Answer:
Angle A = 100°
Angle B = 80°
Step-by-step explanation:
Supplementary angles sum 180°
Angle A to Angle B ratio is 5:4, you can write that ratio using a factor.
Angle A = 5x
Angle B = 4x
Since the sum is 180°
Angle A + Angle B = 180°
5x + 4x = 180°
9x = 180°
x = 20°
Replacing x = 20°
Angle A = 5(20°) = 100°
Angle B = 4(20°) 80°
Answer:
1400
Step-by-step explanation:
it will be easier to first do 30 times 60, which is 180, then subtract the parts
the left up part is 100, the left bottom is 150, the top right is 150, added together, is 400
1800-400
Answer:
g(-1) = 1
Step-by-step explanation:
Synthetic division is by far the fastest way to evaluate this function at x = -1. Set up synth. div. as follows:
-1 ) 1 6 12 8
-1 -5 -7
----------------------
1 5 7 1
since the remainder is 1, g(-1) = 1
Answer:
710
Step-by-step explanation:
7(1)3≈710 (after 1 is coming 3, and it's less than 5, so 1 remains the same, and 3 turns 0)
