The sides of the right triangle are as follows:
AC = 3.2 metres
AB = 12.4 metres
How to solve right triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a right triangle is 180 degrees.
Therefore, the sides of a right triangle can be found using trigonometric ratios.
Hence, let's find AC
tan 15 = opposite / adjacent
tan 15 = AC / 12
cross multiply
AC = 12 tan 15
AC = 12 × 0.26794919243
AC = 3.21539030917
AC = 3.2 metres
Let's find AB
cos 15 = adjacent / hypotenuse
cos 15 = 12 / AB
AB = 12 / cos 15
AB = 12 / 0.96592582628
AB = 12.423314503
AB = 12.4 units

For breakfast, Sarah can choose eggs, granola or oatmeal as a main course, and orange juice or milk for a drink. Sarah says that the sample space for choosing one of each contains 32 = 9 outcomes. What is her error? Explain. Because there are choices for the first item and for the second, there are possible outcomes.
Answers
Answer:
The explanation is given below
Step-by-step explanation:
Her error is that she multiplied the possibilities of her meal that involves eggs with milk, granola & oatmeal but the possibilities involves orange juice with egg and granola & oatmeal
Now
If she choose milk so she can select eggs, granola, and oatmeal so there are 3 possibilities also with the orange juice there is 3 possibilities
So, the sample space is
= 3 + 3
= 6 outcomes

D. 8x + y = 22
-2x - 5y=4
E5x - y = -17
x + 4y = 5
Answers
Answer:
Options B and E.
Step-by-step explanation:
We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).
The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.
Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.
A)
6x - y = 15
-3x + 4y = -18
In the first equation we have:
6*(-3) - (2) = 15
-18 - 2 = 15
-20 = 15
This is false, so we can discard option A.
B)
2x + y = -4
3x + 2y = -5
In the first equation we have:
2*(-3) + 2 = -4
-6 + 2 = -4
-4 = - 4
This is true, now let's look at the other equation.
3*(-3) + 2*(2) = -5
-9 + 4 = -5
-5 = - 5
This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.
C)
x + 8y = 19
4x - 5y = 2
In the first equation we have:
(-3) + 8*(2) = 19
-3 + 16 = 19
13 = 19
This is false, then we can discard option C.
D)
8x + y = 22
-2x - 5y=4
In the first option we have:
8*(-3) + 2 = 22
-24 + 2 = 22
-22 = 22
This is false, so we can discard option D.
E)
5x - y = -17
x + 4y = 5
In the first option we have:
5*(-3) - (2) = -17
-15 - 2 = -17
-17 = -17
This is true, now let's look at the other equation:
(-3) + 4*(2) = 5
-3 + 8 = 5
5 = 5
This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.
Then the correct options are B and E.

Graph a line with a slope of -3 that contains the point (4, -2).
(Just tell me where to put the points please)

(4, -2), (3, 7), (5, 1), (6, -2), (7, -5)
Step-by-step explanation:
These are a few of the points, so you can just connect them!
Hope this helped! :)
Answer:
Step-by-step explanation:
If you have both the slope and a point on the line, use the point-slope formula y - k = m(x - h), which here is y + 2 = -3(x - 4).
Now you can choose a few x values at random and calculate the associated y values. Let's try x = -1, x = 3, x = 0:
For x = -1: y + 2 = -3(-1 - 4), or y = -2 -3(-5) = -2 + 15 = 13. The point is (-1, 13).
For x = 3, we get y + 2 = -3(-1), or y = -2 + 3 = 1. The point is (3, 1).
For x = 0, y = -2 - 3(-4), or y = -2 + 12 = 10. The point is (0, 10).
Plot these three points and draw a line through them.

Step-by-step explanation:
3x-160 = x+20. Why you may ask? they are corresponding angles which makes them congruent. 2x = 180, so x = 90
Answer:
90
Step-by-step explanation:
angle 1 and 4 are equivalent so:
3x - 160 = x + 20
_________________
3x - 160 = x + 20

3x = x + 180

The Becks buy a plastic tarp to cover their firewood. A rectangle that is eight and one-third yards long and six and three-fourths yards wide. Part A Which equation models the best estimate for the area of the tarp?
Answers
Answer:
56 1/4 yards
Step-by-step explanation:
Area of the tarp = length × width
Length = 8 1/3 yards
Width = 6 3/4 yards
Area of the tarp = length × width
= 8 1/3 yards × 6 3/4 yards
= 25/3 × 27/4
= (25 * 27) / (3 * 4)
= 675 / 12
= 56 1/4 yards
Area of the tarp = 56 1/4 yards
