Answer:

m<A = 30

Step-by-step explanation:

The right square is a 90 degree angle

All angles in a triangle add up to 180 so:

x + 37 + x + 67 + 90 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

<A:

x + 37

-7 + 37

Answer:

A=30

Step-by-step explanation:

Set your equation up as following:

180=90+(x+37)+(x+67)

180=90+37+67+2x

180-90-37-67=2x

-14=2x

-14/2=x

-7=x

Angle A = x+37

A=-7+37

A=30

Excellence Middle School charges $6.25 for students from all grade levels to attend the school dance. If S represents the number

vlabodo [156]

The answer would be b: 6.25(s+g)

you can already cancel out c., as there’s no way it could be 13.50

since it says it’s $6.25 dollars for all grades and you would be trying to find both 7th and 8th graders, you would need to multiply both variables by the amount they need to pay. in this case, $6.25.
