Find the measure of each of the angles. Don’t forget to label your answer
user100 [1]

Answer:

a=125^o

b=55^o

c=55^o

d=55^o

e=125^o

f=55^o

Step-by-step explanation:

step 1

Find the value of x

we know that

(2x+25)^o=(x+75)^o ----> by alternate interior angles

solve for x

Group terms

2x-x=75-25

x=50

step 2

Find the measure of angle a

we know that

a=(x+75)^o ----> by vertical angles

substitute the value of x

a=(50+75)=125^o

step 3

Find the measure of angle b

we know that

a+b=180^o ----> by supplementary angles (form a linear pair)

we have

a=125^o

substitute

125^o+b=180^o

b=180^o-125^o=55^o

step 4

Find the measure of angle c

we know that

c=b ----> by vertical angles

we have

b=55^o

therefore

c=55^o

step 5

Find the measure of angle d

we know that

d=b ----> by corresponding angles

we have

b=55^o

therefore

d=55^o

step 6

Find the measure of angle e

we know that

e=a ----> by alternate exterior angles

we have

a=125^o

therefore

e=125^o

step 7

Find the measure of angle f

we know that

f=d ----> by vertical angles

we have

d=55^o

therefore

f=55^o

If M <1 = 115 degrees what is m <2
SIZIF [17.4K]

Answer:

M<2= 65

Step-by-step explanation:

The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.

You would use angle addition postulate to find the answer so M<1 + M<2 = 180.

Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180

Then you would subtract 115 from 180 in which you would get M<2 = 65

Only do question 4<br><br> 50 points<br><br> Topic: Percentage
Sergeu [11.5K]

Answer:

a 1

b 6

c 15

Step-by-step explanation:

101% 101/100 = 1 1/100

is 1  complete 100 grid and 1/100 of another grid so you will need 2 grids

589% 589/100 = 5 89/100

is 5 complete 100 grids and 89/100 of another grid so you will need 6 grids

1450% 1450/100 = 14 50/100

is 14 complete grids and 50/100 of another grid so you will need 15 grids
