The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.
The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.
The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.
The fourth is a right triangle because it has a right angle, and it is a s</span><span>calene because none of the sides are congruent.</span>
Answer:
30/75 2/5
Step-by-step explanation:
there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75. This can be simplified to 2/5 if both sides are divided by fifteen.
To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%
Answer with Step-by-step explanation:
We are given that



Compare with slope-intercept form

Where m=Slope of line
b=y-intercept
a.We get slope=m=1
b.b=81
c) To find the x- intercept
Substitute y=0


x-intercept at x=-81
Answer:
Angle 3 is 75 degrees
Angles 8 is 105 degrees
Step-by-step explanation:
Angle 3: One line t, angle 3 and the one measure 105 are supplementary and equal to 180 degrees. Subtract 105 from 180.
Angles 8: The angle that measures 105 and angle 8 are alternate exterior angles. This means both angles are equal.
Hope this helps!
