Answer:
70 degrees
Step-by-step explanation:
If cosm<A = 342/1000, we are to find the value of a
Take arccos of both sides
cosm<A = 342/1000
cosm<A = .342
arccos(cosm<A) = arccos(0.342)
m<A = arccos(0.342)
m<A = 70 degrees
Hence the measure of m<A is 70 degrees

Answers
Answer:
Step-by-step explanation:
we have a right triangle,
to find out the hypotenuse, h
H^2=13^2+4^2
H^2=169+8=177
The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
What is Pythagoras theorem?Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building
As per the condition, We have a right triangle.
To find out the hypotenuse x
By Pythagoras theorem,
⇒ x² = 13² + 4²
⇒ x² = 169 + 8
Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.
Hence, the correct answer would be an option (A).

Answer:
arc 1 = 108 degrees
angle 2 = 54 degrees
Step-by-step explanation:
180 - 72 = 108 (half circle -72)
draw a line from center of circle to tangent point.
this line is perpendicular to the tangent line.
all radii are equal.
then, triangle made with the new line is isosceles with two equal angles.
those angles are 36 degrees each (180 - 108 = 72, 72/2 = 36)
line drawn from center to tangent point is 90 degrees so:
90 - 36 = 54 degrees

Determine how many feet each member of Lola's family walked.
Lola's pet turtle walked 10 feet, and then half that length again.
Lola's baby brother walked 3 feet, and then half that length again.
Lola's hamster walked 6.5 feet, and then half that length again.
Lola's mom walked x feet, and then half that length again.
Answers
Step-by-step explanation:
Lola's pet turtle walked 10 feet, and then half that length again. This means that Lola's pet turtle walked:
= 10 + (1/2 × 10) = 10 + 5 = 15 feet
Lola's baby brother walked 3 feet, and then half that length again. Total length walked will be:
= 3 + (1/2 × 3) = 3 + 1.5 = 4.5 feet
Lola's hamster walked 6.5 feet, and then half that length again. Total length walked will be:
= 6.5 + (1/2 × 6.5) = 6.5 + 3.25 = 9.75
Lola's mom walked x feet, and then half that length again. Total length walked will be:
= x + (1/2 × x) = x + 0.5x = 1.5x
Total feet walked by the whole member of the family will be:
= 15 + 4.5 + 9.75 + 1.5x
= 29.25 + 1.5x
Answer:
turtle: 10 + 5 = 15
brother: 3 + 1 1/2 = 4 1/2

The length of Kathy's rectangular
garden is 4 feet more than the width. If
the perimeter of her garden is 40 feet,
what is the length of Kathy's garden?
Answers
Half the perimeter is the length + the width.
Let the width = x
The length is x + 4. ( 4 feet more than the width)
Now you have x + x + 4 = 20
Combine like terms:
2x + 4 = 20
Subtract 4 from both sides:
2x = 16
Divide both sides by 2:
X = 8
The width is 8 feet
The length is 8 + 4 = 12 feet

If a solution to a linear system of equations is no solution, then what must be true about the graph of the system?
Answers
Answer:
Step-by-step explanation:
The lines are parallel to one another.
A linear system of equations has no solution if the graphs are parallel and the two lines never meet.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.
A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.
Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.
Answers
Answer:
depends on the other side, so... maybe
Step-by-step explanation:
If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.
Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25. If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25
