Answer:

Step-by-step explanation:

2a the answer is 50

we know that the sum of angles in a triangle is 180, so we do 180-90-40 to find the missing angle because two of the angle measurements are already given.

2b the answer is 76

we know that the sum of angles in a triangle is 180, so we do 180-52-52 to find the missing angle because two of the angle measurements are already given.

2c the answer is 36

we know that the sum of angles in a triangle is 180, so we do 180-126-18 to find the missing angle because two of the angle measurements are already given.

3a the answer is 134

we know that the measure of an exterior angle is the sum of the two remote interior angles, so we do 61+73

3b the answer is 126

we know that the measure of an exterior angle is the sum of the two remote interior angles, so we do 90+36

3c the answer is 92

we know that the measure of an exterior angle is the sum of the two remote interior angles, so we do 48+46

the last one, the answer is 105

to find the measure of an angle is a regular polygon, use the formula

((n-2)*180)/n  n = the number of sides

we use this to find the angle measure of the octagon, and we get 135

we use this same formula to find the angle measure of the hexagon, and we get 120

add both of those up 120+135 = 255

then subtract that from 360 because the 360-255 = 105

How to solve 4+|7-m|=5
notka56 [123]
When
|a|=b
assume
a=b and -a=b
so

4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1

7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6

-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8

m=6 and 8

Tamar has four more quarters than dimes. If he has a total of $1.70, how many quarters
erma4kov [3.2K]
<h3>Answers:</h3><h3>6 quarters</h3><h3>2 dimes</h3>

================================================

Work Shown:

d = number of dimes

q = number of quarters

q = d+4 since she has 4 more quarters than dimes

$1.70 = 170 cents

10d = value of all the dimes in cents

25q = value of all the quarters in cents

10d+25q = total value of all the coins in cents

10d+25q = 170

10d+25( q ) = 170

10d+25( d+4 ) = 170 .... plug in q = d+4

10d+25d+100 = 170 .... distribute

35d+100 = 170

35d = 170-100 ..... subtract 100 from both sides

35d = 70

d = 70/35 ... divide both sides by 35

d = 2

He has 2 dimes

q = d+4

q = 2+4

q = 6

He also has 6 quarters

------------------

Check:

1 dime = 10 cents

2 dimes = 20 cents ..... multiply both sides by 2

1 quarter = 25 cents

6 quarters = 150 cents ..... multiply both sides by 6

(2 dimes) + (6 quarters) = (20 cents) + (150 cents) = 170 cents

This confirms the answers.
