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

Mathematics
1 answer:
lions [1.4K]3 years ago
8 0

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

Divide £12 between mick and sharon in the ratio 2:4
antiseptic1488 [7]

Answer:mick share is £4 while Sharon share is £8

Step-by-step explanation:

Money to be shared=£12

Mick : sharon=2:4

Sum of ratio=2+4=6

Mick share=2/6 x 12

Mick share=(2x12)/6

Mick share=24/6

Mick share=4

Sharon share=4/6 x 12

Sharon share=(4x12)/6

Sharon share=48/6

Sharon share=48/6

Sharon share=8

Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
aliya0001 [1]

Answer:

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

        = x² - 16x + 64 + 3x - 24 + 2

        = x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

             = 64 + 104 + 42

             = 210

I need to solve for x, help please.
BaLLatris [955]

Answer:

x = 52   i hope this helps!   :)

Step-by-step explanation:

so first you gotta realize that every triangle has an interior angle measurement sum of 180 degrees

so we are given 3 angles   74 degrees  x + 2  and x

we now are going to put this into an equation   74 + x + 2 + x = 180

now lets combine like terms to get   76 + 2x = 180

then we are going to subtract the 76 from both sides   2x = 104

now lets divide both sides by 2   x = 52

so x = 52

we can plug in the value of x into both of the other equations to find the angle measurement

52 degrees

52 + 2 = 54 degrees

and then we have 74 degrees

add the 52, 54, and the 74 to make sure it is equal to 180 degrees

106 + 74 = 180

so yes, x does indeed equal 52 degrees
