A triangle cannot contain two right angles.

Mathematics
1 answer:
Bas_tet [7]3 years ago
6 0

Answer:

True

Step-by-step explanation:

A triangle must have 3 angles which add up to 180 degrees

A right angle is 90 degrees so if you added 90 to 90 (two right angles) it would be 180.  This is true since the two angles cannot be a triangle.

I am not sure what the question was but i am guessing you needed proof.

(High points) please solve with explanation. Legit answers only thank you!

Step-by-step explanation:

The x-intercept is at (-3, 0). To find the slope of the perpendicular line, let's rewrite the equation to its slope-intercept form, which is

y = (2/3)x + 2

This means that the perpendicular line has a slope m = -3/2. So the slope-intercept form of this new line is

y = -(3/2)x + k. Since this line passes through (-3, 0), we cal solve for k:

0 = -(3/2)(-3) + k or k = -9/2

So our equation becomes (slope-intercept form)

y =   - \frac{3}{2}x -  \frac{9}{2}

or in its standard form,

3x + 2y + 9 = 0
