left side is not equal to the right. It means that is not right triangle
Step-by-step explanation:
No, triangle ABC is a right angle triangle.
What is triangle ?Triangle is a two dimensional shape having three side and sum of all angles is equals to [tex]180^0[/tex].
We have,
[tex]a=15[/tex], [tex]b=12[/tex] and [tex]c=21[/tex]
So,
To be a right angle triangle it must satisfy the Pythagoras triangle.
i.e.
[tex]H^2=P^2+B^2[/tex]
So,
[tex]21^2=15^2+12^2[/tex]
[tex]441=225+144[/tex]
[tex]441\neq 369[/tex]
So, triangle ABC is not a right angle triangle as it does not satisfy the Pythagoras triangle.
Hence, we can say that No, triangle ABC is a right angle triangle.

Answer:
Rs. 1000Step-by-step explanation:
Let the marked price is x
Discount 4% ⇒ x - 4% = 0.96xCP = Rs. 800 Profit after discount = 20%SP = 800 + 20% = 800*1.2 = Rs. 960Now we have below equation:
0.96x = 1.2*8000.96x = 960x = 960/0.96x = 1000MP is Rs. 1000

A point is in Quadrant 3 and on the unit circle. If its x-coordinate is -4/5, what is the y-coordinate of the point?
Answer:
The y-coordinate of the point is -3/5
Step-by-step explanation:
Here, we want to get the y-coordinate of the point
when we talk of the unit circle, we mean a circle that has its radius equal to just 1 unit
Now, on the third quadrant, we have the x axis value as negative, and also the y axis value as negative
In the unit circle, the Pythagoras’ theorem works for all quadrants; with the radius representing the hypotenuse of the right triangle, the x and y coordinates value represents the other sides of the triangle
Mathematically, from the theorem;
the square of the hypotenuse (radius of the unit circle) equals the sum of the squares of the two other sides
Thus, we have it that;
1^2 = (-4/5)^2 + y^2
1 = 16/25 + y^2
y^2 = 1 - 16/25
y^2 = 9/25
y = √(9/25)
y = +3/5 or -3/5
But since the y-coordinate value is supposed to be negative, we have to choose y = -3/5 as our answer (for the third quadrant)

significant figures.
Answer:
93.1
24.83
24.13
2755
12.75
0.151
Step-by-step explanation:
Given :
21.1 + 45.99 + 26.0 = 93.09
15.55 + 21.61 - 12.333 = 24.827
14 + 0.8 + 9.33 = 24.13
14.5 * 190 = 2755
5.1 * 2.5 = 12.75
0.15 ÷ 0.991 = 0.151

Each term is being doubled and the sign is reversing for every term. So -10 doubled and flipping the sign results in 20. Doubling 20 and flipping the sign results in -40. So on and so forth.
Determine this one algebraically
Answer:
x = 5
y = 5
Step-by-step explanation:
In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...
2x - x = 5
1x = 5
x = 5
Now we plug that value of x into the second equation
4x - 2y = 10
4(5) - 2y = 10
20 - 2y = 10
-2y = -10
y = 5
Finally, we can see that both x and y have a value of 5.
