If one of the acute angles of a right angled triangle is 55 , calculate the remaining angle​

Mathematics

Answer:

35 degrees

Step-by-step explanation:

To start off, the term "acute angle" means less than 90 degrees. In this case, the acute angle is 55 degrees.

The type of triangle mentioned in the question is a right-angled triangle, meaning it has a right triangle (90 degrees) along 2 other triangles. A triangle is generally 180 degrees. So now that we know the value of 2 out of 3 angles we do simple math.

Assume the unknown angle is A.

55 + 90 + A = 180

A = 35

2. Find the equation of the perpendicular bisector of line PQ where the co-ordinates of P and Q are P (-2, 8) and Q (4,7)
Novosadov [1.4K]

Answer:

2y - 12x = 3

Step-by-step explanation:

gradient of line PQ= (7-8)/ 4+2

-1/6

gradient of perpendicular bisector of line PQ=

-1 ÷ -1/6

-1× -6

6

coordinates of the midpoint of line PQ

(-2+4)/2, (8+7)/2

(1, 15/2)

the perpendicular bisector passes through the midpoint of line PQ

Equation of the perpendicular bisector

y - 15/2 = 6(x - 1)

multiply through by 2

2y - 15 = 12(x - 1)

2y - 15 = 12x - 12

2y - 12x = 3

Miguel and Maria are washing the windows in their home. Together, they can complete the task in 1 hours. If Maria can wash windo
Orlov [11]
For this case, the first thing we must do is define variables.
 x: amount of time Miguel uses to complete the task.
 y: amount of time Maria uses to complete the task.
 We write the system of equations:
 x + y = 60
 y = (1/2) x
 Solving the system we have:
 x = 40 minutes
 y = 20 minutes
 Answer:
 
it take her to wash them by herself about:
 
y = 20 minutes

What is x²+x-30 as a binomial?
Zolol [24]
X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
