Answer:
a) 15*15=225 that is the area
b)see picture that I drew (sorry I have terrible drawing skills on a computer) but in a an isosceles triangle the two legs are congruent and the base is not when you cut a square diagonally as you have done this one the base will not be the same as the other two legs.
Step-by-step explanation:
If the square sum of the perpendicular and base is less than the square of hypotenuse then the angle will be an obtuse angle. Then the correct option is C.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras is the sum of the square of two sides is equal to the square of the longest side. And it is given as
P² + B² = H²
A triangle with side lengths of 6 cm, 10 cm, and 12 cm.
We know that if the square sum of the perpendicular and base is greater than the square of hypotenuse then the angle will be an acute angle.
Ans if the square sum of the perpendicular and base is less than the square of hypotenuse then the angle will be an obtuse angle.
Then we have
6² + 10² < 12²
Then the angle will be an obtuse angle.

For triangles, area is 1/2 base times height
8. Base 15 1/4 and height 18. Base and height can be flipped around to make the math easier, so 1/2(18)(15 1/4) = 9(15 1/4) = 9(61/4) = 549/4= 137 1/4 sq inches
9. Base 13 and height 11. Area = (1/2)(13)(11)= (13/2)(11) = 143/2 = 71 1/2 sq inches
10. Same thing again. Base = 30, height = 20, so area = (1/2)(30)(20) = 15(20) = 300 square km.
11. Base = 8, height = 5, so (1/2)(8)(5)= 4(5)= 20 square feet.
12. Base = 5, height = 3, so area = (1/2)(5)(3)= (5/2)(3)= 15/2; for 200 tiles we would take (15/2)(200)= 15(100) = 1500 square cm
13. Monica forgot to multiply base and height by 1/2.
Answer:
12
Step-by-step explanation:
25%=1/4
of=*
3=1/4x
3 divided by 1/4 or 0.25 =12
