What are the measures of Angles a, b, and c? Show your work and explain your answers.

a) 30 degrees

b)60 degrees

c)105 degrees

Step-by-step explanation:

A) Angel A is the Vertical Angle of the 30 degree angle right across from it.

B) Since we know that Angle A is 30 degrees and that another agle within this triangle is a right angle. and remembering that every triangles angles all add up to 180 degrees that would make angle b 60 degrees.

C) remembering that any line is 180 degrees then we can subtract 75 from 180 to get 105 degrees for Angle C because its the Supplement to to 75.

step-by-step explanation:

goog be able to you with that maybe

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
