28.75 degrees

Step-by-step explanation:

The missing angle in the triangle and 120 add up to 180 so the missing angle must be 60 degrees

all the angles of the triangle add up to 180 degrees so

x + 3x + 5 + 60 = 180

4x = 180 - 65

4x = 115

x = 28.75

x = 28.75°

Step-by-step explanation:

First, you have to solve for the angle that is supplementary with 120°.

180° - 120° = 60°

The inside angles must add up to 180°, so the equation will be:

(3x+5)° + x° + 60° = 180° ––Now combine like terms (the x's)

(4x + 5)° + 60° = 180° ––Combine the like terms on the left (5 and 60)

4x° + 65° = 180° –– Get the x term all alone by subtracting 65 from both sides

4x° = 115° –– Divide both sides by 4 to get x by itself

x = 28.75°

Check by substituting:

[(3•28.75)+5]° + 28.75° + 60° = 180

(86.25 + 5)° + 28.75° + 60° = 180°

91.25° + 28.75° + 60° = 180°

120° + 60° = 180°

180° = 180°

This is correct.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
