Angle B= 27, a=28ft, b=18ft solve for measurement(s) of angle c

Answers

Answer 1

Answer: In a triangle, the sum of the angles is 180 degrees. Therefore, if we know two of the angles, we can use this property to find the measure of the third angle.

In this case, we are given angle B = 27 degrees and we want to find the measure of angle C. We can use the following equation to find angle C:

Angle B + Angle C + Angle A = 180

27 + Angle C + 90 = 180

Angle C = 180 - 27 - 90

Angle C = 63 degrees

Additionally, we can use the Law of Cosines to find the measure of angle C.

c² = a² + b² - 2ab * cos(C)

c² = 28² + 18² - 2 * 28 * 18 * cos(C)

c² = 784 + 324 - 1008 * cos(C)

c = √(1108 - 1008*cos(C))

We know that cos(C) = (a² + b² - c²) / 2ab

cos(C) = (784 + 324 - c²) / (22818)

We can substitute the value of c² that we obtained from the first equation and find cos(C) and thus angle C.

So the measure of angle C is 63 degrees.

A. 2.23
OB. 4.47
O c. 2.44
D.2

Answers

Answer:

The distance A’C’ is 4.47 units

Step-by-step explanation:

Before we go on, we need to get the appropriate transformation

Mathematically, we have a 90 degrees clockwise rotation yielding the following;

(x,y) to (-y,x)

A is (-4,1)

C is (-2,5)

By transforming, we have

A’( -1,-4)

C’ (-5,-2)

To get the magnitude of the line segment, we are going to use the distance formula between points

We have this as;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(-5-(-1))^2 + (-2-(-4))^2

D = √(-4)^2 + (2)^2

D = √(16 + 4)

D = √20

D = 4.47 units

Answer:

D

Step-by-step explanation:

To keep it short, refer to triangle exterior angle theorem.

Edit: If you want the full explanation,

A isn't the answer. The triangle exterior angle states that the measure of the 2 triangle interior add up to the the exterior angle of the other interior angle within the triangle.

Meaning that

measure of angle 1 equal the measure of 3 and 4 combined.

B. is wrong they are equal to each other because angle 2 is equal to angle 2

angle 1 is equal to angle 3 and 4

So they are equal

C.Wrong unless it a 30 60 90 triangle or 45 45 90 triangle, C is wrong

D. is right since measure of angle 4 and angle 3 add up to angle 1, angle 4 would be lesser than angle 1.

Answer:

x = 135

Step-by-step explanation:

The angles at the bottom are right angles (90°)

The sum of interior angles in this rectangle is equal to 720°

Find the sum of interior angles

4x + 180 = 720 subtract 180 from both sides

4x = 540 divide both sides by 4

x = 135 this is also giving us the measure of missing angles.

Well if 4 blue circles + 1 red triangle = 2 green squares + 1 red triangle, then 2 blue circles = 1 green square

Then 3 red + 2 blue = 1 green + 2 blue, so 3 red = 1 green

If we know these facts then

3 red = 2 blue = 1 green

So the bottom one is 6 reds = 2 greens, or 1 green + 2 blue.

Step-by-step explanation:

The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.
