Answer:

∠ 3 and ∠ 2

Step-by-step explanation:

Complementary angles sum to 90°

Since ∠ 1 = 90° and ∠ 1, ∠ 2 and ∠3 lie on a straight line, then

∠ 1 + ∠ 2 + ∠ 3 = 180°, that is

90° + ∠ 2 + ∠ 3 = 180° ( subtract 90° from both sides )

∠ 2 and ∠ 3 = 90°

Since they sum to 90° then

∠ 3 and ∠ 2 are complementary

What is the value of f(4) in f(x)=3x-6

vodka [1.7K]

F(4) value is 6.
I believe it would work like this:
f(x) is being turned into f(4), so 4 would equal x. Put 4 into the equation 3x-6, and you get 12-6, which gives you 6. So the value of f(4) is 6. I hope this helps!

A simplified model of the human blood-type system has four blood types: A, B, AB, and O. There are two antigens, anti-A and anti

dexar [7]

Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.

Step-by-step explanation:

S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}

If AntiA reacts and AntiB reacts = AB (A∩B)

If AntiA does not react and AntiB does not react= O (A'∩B')

If AntiA reacts and AntiB does not react= A (A∩B')

If AntiA does not react and AntiB reacts= B (A'∩B)
