WILL MARK AS BRAINIEST!!!!!!! In this triangle, which of the following is true?
prisoha [69]

Answer:

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180

x = 180° - (90 + 35)° = 180° - 125° = 55°

----------------------------------------------------------

Since the triangle is right use the cosine ratio to solve for b

cos35° = \frac{adjacent}{hypotenuse} = \frac{b}{20}

Multiply both sides by 20

20 × cos35° = b, hence

b = 16.38 ( to 2 dec. places )

8. There are 3 people who work full-time and are to work together on a project, but their total time on the project is to be equ
Mama L [17]

Answer:

1/6 of the third workers time

Step-by-step explanation:

one of the people is budgeted for 1 /2 of his time to the project and a second person for 1/3 of her time

Let x be the third workers time

Let the completed job time = 1

Time taken for 3 workers to complete the job = 1

\frac{1}{2}+ \frac{1}{3} + x= 1

now we solve for x

LCD = 2*3 = 6

We multiply the whole equation by 6

\frac{1}{2}*6+ \frac{1}{3}*6 + x*6= *6

3 + 2 +6x = 6

5 + 6x = 6

subtract 5 on both sides

6x = 1

divide both sides by 6

x= \frac{1}{6}
