Answer:

136 Degrees

Step-by-step explanation

Set up as (3x+11) + (5x-9) = 90

then solve for x using algebra.

you can do this because angle NSO and RSQ are eqaul once you know x you will be able to solve all the other angles and subtract from 360 (the total angle) to find NSR.

Steps:

3x+11+5x-9 = 90

8x+2=90

x= 11

Solve 3(11)+11 = 44

add known angles:

44+90+90 = 224

360-224 = 136 degrees

We use concepts like complimentary angles and vertical angle theroem.

Only do question 15 50 points Topic: Percentage

Varvara68 [4.7K]

Answer:

see below

Step-by-step explanation:

The total number of trees is

567+324+156+89+678 =1814

Percent fir = 567/1814 = .312568908=31.26 %

Percent pine = 324/1814 = .178610805=17.86%

Percent larch = 156/1814 =.085997795=8.60%

percent cedar = 89/1814 =.049062845=4.91%

Percent hemlock = 678/1814 = .373759647=37.38%

The total should be 100 %

31.26+17.86+8.60+4.91+37.38=100.01 ( rounding error because we rounded to the hundredths place)
