Dmitriy789 [7]3 years ago
5 0

Step-by-step explanation:

Area of Traingle=1/2×b×h

192cm²=1/2×24×h

192cm²=12×h

h=192/12

h=16cm

Hypotenuse ²=Base²+Altitude ²

Hypotenuse ²=12²+16²

Hypotenuse ²=144+256

Hypotenuse ²=400

Hypotenuse =20cm

Perimeter=20+20+24

=64cm

Yes, the triangle is right angled.

Step-by-step explanation:

Given lengths are;

11 yards, 60 yards and 61 yards

From pythagoras theorem;

The sum of square of shorter lengths is equal to square of larger side.

Here;

a = 11 , b = 60 , c = 61

a^2+b^2=c^2\\(11)^2+(60)^2=(61)^2\\121+3600=3721\\3721=3721

As it satisfies the condition of Pythagoras theorem, the triangle is right angled.

Yes, the triangle is right angled.

Consider the line y equals 2 over 5 x plus 4.
crimeas [40]

the parallel linear equation is:

y = (2/5)*x - 3

<h3></h3><h3>How to find the parallel line?</h3>

Two lines are parallel if the lines have the same slope but different y-intercept.

Here we know the line equation:

y = (2/5)*x + 4

Then a parallel line is of the form:

y = (2/5)*x + c

Where c is different than 4.

We want this line to pass through (5, -1), then:

-1 = (2/5)*5 + c

-1 = 2 + c

-1 - 2 = -3 = c

Then the parallel linear equation is:

y = (2/5)*x - 3

You multiply the numbers 
4X0.55= 2.2

but since you need that 0.2 to complete the self you round up to 3 <span />

(1/sin∅)(sin∅/cos∅)

(sin∅)/(sin∅cos∅)

1/(cos∅)

sec∅

csc²∅tan²∅sin∅

1/(sin²∅) * tan²∅ * sin∅

tan²∅/sin²∅ * sin∅

tan²∅/sin∅
