Answer:

28 and 7

35

Step-by-step explanation:

The area of a triangle is base*height/2, no matter the shape.

So the big one is 8*7/2 = 28 in²

And the little one is 2*7/2 = 7 in²

The total trapezoid therefore has an area of 28+7=35 in²

Answer:

\sf x=\boxed{18.21}

Step-by-step explanation:

Assuming this is a right triangle.

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse

Given:

  • \theta = 35°
  • O = x
  • A = 26

\implies \sf \tan(35^{\circ})=\dfrac{x}{26}

\implies \sf x=26\tan(35^{\circ})

\implies \sf x=18.20539599...

Therefore, x = 18.21 (nearest hundredth)

The mean is the average of the numbers: a calculated "central" value of a set of numbers.

Therefore: If the amount spent on books per month by all her classmates is leveled that amount would be $30

To calculate it: add up all the numbers, then divide by how many numbers there are
