This is a vertical angle, and vertical angles are equal to each other. So your equation would be 46 = x + 5. Now you solve for x by subtracting 5 on both sides. You are left with 41 = x, so there is your answer.

Answer:

Step-by-step explanation:

The sum of the internal angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

Sholpan [36]

Trey will read 18 pages in 45 minutes.

This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18

Out of 10 students, 1 student is wearing brown shoes, 7 students are wearing black shoes. What fraction of the students are not

iVinArrow [24]

Answer:

$Fraction=\frac{1}{5}$

Step-by-step explanation:

Total number of students $=10$

Students wearing brown shoes $=1$

Students wearing black shoes $=7$

Number of students wearing black or brown shoes $=1+7=8$

Number of students not wearing brown or black $=10-8=2$

Fraction of students not wearing brown or black $=\frac{2}{10}=\frac{1}{5}$

Sam walks from home to his school which is 0.75 miles away in 12 minutes. How fast was he walking?

SCORPION-xisa [38]

Answer:

v = 3.75 mph

Step-by-step explanation:

Constant speed motion

An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.

Expressed in a simple equation, we have:

$\displaystyle v=\frac{d}{t}$

Where

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.

t=12/60 = 0.2 hours. Now compute the speed:

$\displaystyle v=\frac{0.75\ mi}{0.2 \ h}$

v = 3.75 mph
