What is measure of angle C?Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answers

Answer:

The measure of angle C is 36.86°

Step-by-step explanation:

Given : A right angled triangle with right angle at B.

We have to find the  measure of angle C.

Consider the given right triangle.

Using trigonometric ratio,

Since, we know tangent is the ratio of perpendicular to base

Using \tan\theta =(Perpendicular)/(base)  

Here, for angle C we have base = 4 cm  and perpendicular = 3 cm

Thus,  \tan C =(3)/(4)

Taking \tan ^(-1) both side, we have,

\tan ^(-1)(\tan C)=\tan ^(-1)((3)/(4))

C=\tan ^(-1)((3)/(4))

C=36.86^(\circ \:)

Thus, The measure of angle C is 36.86°

So you basically plot a point of the y axis on 7 then since the slope is -3x you have to go down 3 and to the right 1 and keep going then you have to do the same but opposite, go up 3 times and to the left 1 unit.

Tabitha wants to hang a painting in a gallery. The painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?

(See picture attached below)

Answer Choices:
A. x2 + 15x − 2 = 0
B. x2 + 15x + 58 = 0
C. 4x2 + 30x − 2 = 0
D. 4x2 + 30x + 58 = 0

Answers

If the total area of the painting and the frame is 58 sq ft, we have the equation:
(8 + 2x)(7 + 2x) = 58

Expanding the equation,
56 + 30x + 4x^2 = 58

Combining like terms and arranging the equation, we have:
4x^2 + 30x - 2 = 0

Therefore, the answer is
C. 4x2 + 30x − 2 = 0

Write the scale or unit ratio for the problem: There are 48 ounces of soda and 2 cups of ice cream ina batch of punch. How many ounces of soda are needed if 5 cups of ice cream are used to make
punch?
0 48 ounces/2 cups
O 5 cups/2 cups
O 48 ounces/5 cups

Answers

Greetings from Brasil...

Let's apply rule of 3:

  cups             oz

     2     -------   48

     5     -------    X

2 · X = 48 · 5

2X = 48 · 5

X = (48 · 5)/2

48 is the volume of soda, so just multiply that volume by 2/5 to get the new amount of soda...

The number divided by -4 is increased by -63, the result is -45. What is the number?

Answers

x / (-4) + ( -63) = -45 <=> x / ( -4) = 63 - 45 <=> x / (-4) = 18 <=> x = 18 * (-4) <=> x = -72.
X/-4+(-63)=-45 -1/4x-63=-45 -1/4x=18 The number was -72
