The measure of an angles suppliment is 53° more than twice that of its compliment. find the angle.

Anettt [7]

(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.

180-x-180+2x=53
x=53

Final answer: The angle is 53 degrees.

The ratio of the perimeters of two similar triangles is 4:7. The sides of the larger triangles are 10, 12, and 13cm,

rjkz [21]

Answer:

Perimeter = 20cm

The perimeter is 35 for the larger triangle = 7:4 ratio

the perimeter for the smaller triangle = 4:7 ratio

We add up 4+7 = 11 and multiply 35 x 2 = 70.

so that the smaller triangle = 40 = 40:70

35 = 7 and 20 = 4

To find measurements of 20

we have any number over 10 combined will make the smaller sides possible,

Where hypotenuse would be under 10.

H = 6.5 Sides = 6 + 5 does not add up to 20

H = 9 Sides = 7 + 4 does have near equal spaced symmetry.

H = 9 Sides = 5 + 6 is wrong as no symmetry in measure

H = 8 Sides = 7 + 5 is wrong as no symmetry in measure

H = 7 Sides = 6 + 7 is wrong as equal sides

H = 6 sides = 6.5 + 6.5 is wrong as equal sides

H = 11 Sides = 6 + 3 is wrong has no symmetry.

The measurements must be 9cm, 7cm and 4 cm for the smaller triangle

The perimeter adds up to 20cm.

The minute hand of a clock moves from 3 o'clock to 6 o'clock, or 1/4 of a complete revolution. Through how many degrees does it

jarptica [38.1K]

Well, there's 360 degrees in a full circle.
If the hand moves 1/4 of a complete revolution, divide 360 by 4.

$360\div4=90$

The minute hand moved 90 degrees.

Use the given graph to determine the limit, if it exists.

Marina CMI [18]

The limit is the value of the function when you approach the closest possible to the x value without getting to that x value.

The closed point (2,1) is not used to calculate the limit. The closed point (2,1) represents the value of the function at x = 1, but the limit is not the value of the function.

Use the horizontal line that comes from the left and ends at the open point (2,3) to find the limit of f(x) when x approaches to 2 from the left.

That limit is 3, because you can get as close as you want to 3 when you approach x = 2 from the left.

Use the horizontal line that starts at the open point (2-2) and goes to the right, to find the limit of f(x) when x approached to 2 from the right.

That limit is -2 because you can get as close to -2 when you approach x = 2 from the right.

It is important that you know that the definition of limits do not include the value of the function at the point where you want to state the limit.

This result, limit of f(x) when x approaches 2 from the left = 3 and limit of f(x) when x approaches 2 from the right = -2, means that the limit of the function when x approaches 2 does not exist.

The limit exists if and only if the two lateral limits exists and are equal.
