Answer:

Step-by-step explanation:

To solve this, you have to find the area of the square then the area of the triangle, and add them together.

To find the are of a square you multiply the base by the height.

Example: 6 × 6 = 36

To find the area of a triangle you multiply the base by the height and divide it by 2.

Example: 6 × 6 = 36

36 ÷ 2 = 18

Now we add both areas together.

Example: 36 + 18 = 54

there are 266 students watching a play in the auditorium. there 10 rows with 20 students in each row and 5 rows with 8 students

kondor19780726 [428]

Let x = number of students in each of the remaining rows

266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13

Ms. Mwanted to estimate the height of the Republic Plaza building in downtown Denver. She has an app on

Answer:

<em>The height of the bullding is 717 ft</em>

Step-by-step explanation:

<u>Right Triangles</u>

The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.

The tangent ratio for an internal angle A is:

$\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}$

The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.

The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:

$\displaystyle \tan 82^\circ=\frac{h}{100}$
