  • Left to Right<u> </u>

<u>Algebra I</u>

  • Reading a coordinate plane
  • Coordinate (x, y)
  • Slope Formula: \displaystyle m = \frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify points from graph</em>

Point (-2, -3)

Point (3, 7)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute in points [Slope Formula]:                                                               \displaystyle m = \frac{7--3}{3--2}
  2. [Fraction] Subtract:                                                                                           \displaystyle m = \frac{10}{5}
  3. [Fraction] Divide:                                                                                               \displaystyle m = 2

Find the measure of the indicated angle to the nearest degree.
fredd [130]

Step-by-step explanation:

Let the measure of required angle be x degree

\therefore \tan \: x =  \frac{33}{56}  \\  \\ \therefore \tan \: x =  0.589285714  \\  \\ \therefore  \: x =   {\tan}^{ - 1} (0.589285714)  \\  \\  \therefore  \: x =   {\tan}^{ - 1} ( \tan \: 30.510237394 \degree) \\  \\    \huge \red{ \boxed{\therefore  \: x =   31\degree}}

Thus, first option is the correct answer.

THE RIGHT ANSWERRRRRR
Mkey [24]
Area of semicircle = 1/2 the area of a circle:
A_{sc}=\frac{1}{2}  \pi  r^{2}
radius is half the diameter of 6ft.
A_{sc} = \frac{1}{2}  \pi  (3^{2} )=14.13 ft^{2} .
Area of the rectangle:
A_{r} =lw=15*6=90 ft^{2} .
Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.
