I'm gonna guess 17? Don't take my advice i'm not sure.
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
Since the equation is parallel to y=2x-4 that means they have the same slope. Now that you have the slope and fortunately a point, you can solve this by using point slope formula
Which is what I did on the attached picture and just rearrange it after solving to Ax+By=C/2x-y=6
Answer:
its A
Step-by-step explanation:
x + y = 9 equation 1<span> the sum of the digits of a two-digit number is 9
</span>the number formed by interchanging the digits is 27 less than the original number<span>
we are looking at the number xy,
10x+y for x is a tens digit.
10y + x = 10x + y + 27
simplify it,
9y = 9x + 27 divide by 9
</span>x + y = 9 equation 1
y= x + 3 equation 2
by subtitution we put y in equation 1
x + (x+3) = 9
2x = 6
x= 6/2= 3
y = x+3=3+3=6
