triangle on right is the same as the triangle on the left

use pythagorean theorem

hypotenuse will give to the sides of the rectangle

a^2 + b^2 = hypotenuse squared

10.4^2 = 108.16

15.3^2 = 234.09

342.25 = hypotenuse squared

take the square root in both sides

hypotenuse = the square root of 342.25 =

18.5

add up the areas of the 2 triangles and rectangle

triangle area is 1/2 times 10.4 times 15.3 =

79.56

2 triangles areas are 159.12

rectangle area is 18.5 × 7 = 129.5

159.12 + 129.5 = 288.62

answer 1 = 288.62

second question:

to get 1 side take the

square root of 702.25 which is

26.5

to get the perimeter

multiply 26.5 by 4 which is

106

answer 2 is choice B 106

mark has 312 books in his bookcases she has 11 as many fiction books as nonfiction books how many fiction books does mark have?
belka [17]
11 as many fiction books as non fiction.

Fiction books F,  Non Fiction NF

F: NF =  11 : 1

Total ratio 11+ 1 = 12.

Fraction of Fiction books F,  =  11/12

Total books = 312.

Fiction books  =     11/12 * 312 =  286

Fiction books = 286

The missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.

<h3>What is a Triangle ?</h3>

Triangle is a polygon with three sides , three angles and three vertices.

Given is triangle ABC , with sides  a = 8, c = 11, and m∠C=33 degree

The missing angle and side is given by Cosine rule of triangle

c² = a² + b² - 2ab cosC

11² = 8² + b²  - 2* 8 * b * cos 33

57 = b² -13.42 b

b²  -13.42b -57 = 0

b = 16.8

By sine rule

a / sin A = b/sin B = c/sinC

8 / sin A = 11 / sin 33

A = 23.33 degree

Similarly

B = 123.7 degree

Therefore the missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.

Pleaaaaaaaaaase i neeeeeeeeeed help please noo links i need help
Salsk061 [2.6K]

Answer:

BADC

Step-by-step explanation:

-4x + 7 \geq 27  Subtract 7

-4x \geq 20  Divide both sides by -4

x \leq -5  B

3x - 10 < -25  Add 10

3x < -15  Divide by 3

x < -5  A

5(x - 2) > -15  Use distributive property

5x - 10 > -15  Add 10

5x > -5  Divide by 5

x > -1  D

x - 9 < -10  Add 9

x < -1  C
