Answer:
A = 55 degrees
B = 35 degrees
C = 90 degrees
side BA = 4.8 units
side AC = 2.7 units
side BC = 3.9 units
Step-by-step explanation:
Hello!
The things we know:
A = 55 degrees
C = 90 degrees
side BA = 4.8 units
AC = adjacent side
BC = opposite side
AB = hypothenuse
B = 180 - 55 - 90 degrees
B = 35 degrees
Let's find side AC
we can use the cos of theta.
cos(55) = AC/4.8
multiply 4.8 on both sides.
4.8cos(55) = AC
AC = 2.7 units
And now we just have to find BC
to calculate BC we can either use tangent or sin.
I will just use sin
sin(55) = BC/4.8
multiply 4.8 on both sides.
4.8sin(55) = BC
BC = 3.9
And now we know everything about the triangle
Hope I Helped!

Answer:
2 2/35 hours
Step-by-step explanation:
In 1 hour, the total amount of the house that is painted is ...
1/8 + 1/4 + 1/9 = 35/72 . . . of a house
We need to multiply the time (1 hour) by 72/35 to find the number of hours required for one entire house:
72/35(1 h) = 2 2/35 h
It would take them 2 2/35 hours to paint the house working together.
