The area of triangle ABC from the given vertices is gotten as; 7.5

<h3>How to find the area of a triangle?</h3>

We are given the vertices of the triangle as;

A(1, 2)

B(4, 0)

C(1,-4)

The formula for area of a triangle with 3 vertices is;

Area = ¹/₂[x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]

Thus;

Area = ¹/₂[1(0 + 4) + 4(-4 - 1) + 1(1 - 0)]

Area = ¹/₂(4 - 20 + 1)

Area = -7.5

Forty tickets are sold for a raffle with two prizes. You buy two tickets. What is the probability that you will win both prizes
tekilochka [14]
When you first pick a ticket, there are 2 winning tickets and 40 total tickets.  This means that there is a 2/40 chance of your ticket being a winning one.  This fraction can be reduced to 1/20.

After this, there will be 1 winning ticket left and 39 total tickets.  There is a 1/39 chance of the next ticket being a winning one.  We multiply these two fractions together to get our answer.  1/20 * 1/39 = 1/780, so there is a 1/780 chance of having 2 winning tickets.

PLEASE HELP IM CONFUSED
jeka57 [31]

Answer:

178° 35'

Step-by-step explanation:

∠ACB and ∠ACD are supplementary, so they add up to 180°.

First, convert to degrees (there are 60 minutes in a degree).

∠ACB = 1°25' = 1° + (25/60)° = 1.4167°

Now find the supplementary:

∠ACD = 180° − 1.4167°

∠ACD = 178.5833°

∠ACD = 178° 35'
