Answer:

Yes, a triangle with sides 8,15 and 17 is a right triangle.

Step-by-step explanation:

The Pythagorean theorem solely applies to right triangles, and if the sum of the square of the two sides of a triangle equal the square of the hypotenuse, then you have a right triangle.

To set it up, remember that the side opposite 30 degrees will be the smallest of the three numbers, and the side opposite 90 degrees (the hypotenuse) will be the largest, leaving the middle number as opposite 60 degrees. If you solve 8^2 + 15^2, you get 289, which is equal to 17^2.

54 / 12 = 4.5

Then

Change it into a fraction

Write is fraction form 4.5 / 1

Multiply both numerator and denominator by 10 for every number after the decimal point

4.5 × 10

1 × 10

Which will equal 45/10

If ABCD is a parallelogram find the value of unknow size

Keith_Richards [23]

Step-by-step explanation:

Hey, there!!

As it is a parallelogram, remember basic properties of parallelogram,

Their opposite sides are parallel and equal to eachother.
Their opposite angles are equal.
They have properties of parallel lines too.

Now, lets solve your question.

b = (7×10)°

Therefore, b= 70°.

now, (3x+10°)+b=180° { co- interior angle of a triangle sum is 180°}.

or, 3x= 180°-80°

or, x= 100°/3

Therefore, x= 33° { rounding off we get 33}.

w+ b =180°

w+70°=180° { coointerior angles are equal}.

Therefore, w =110°

Hope it helps....
