Solve each triangle – find any missing side and angle measures. Round answers to the nearest tenth.
olga nikolaevna [1]

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!

It takes Bill 8 hours to paint a house. It take Paul 4 hours to paint a house. And it takes Quincy 9 hours to paint a house. How
Margarita [4]

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.
