Answer: it should be 28
Step-by-step explanation: because the way the other problems are solved is the right side of the triangle times the bottom and then adding the left side of the triangle, ( 9x8+7=79 ) ( 5x5+5=30) so to get the answer you’d just multiply 24x3= 72 , then subtract 100-72= 28
X-10 + 2x + 1= 90°
you combine like terms:
x+2x= 3x and -10 + 1 = -9
So,
3x - 9 = 90
+9 +9
3x=99
Divide by 3,
x= 33
First Angle: x-10 (plug in 33 for x)
33-10 = 23°
Second Angle: 2x + 1 (plug in 33 for x)
2(33)+1
66+1= 67°
To Check if it’s correct and make a 90° angle:
Add 67° plus 23° which equals 90°
First angle: 23°
Second angle: 67°

522,000. This is most likely a question meant to trick you.
It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation where s is the length of the side.
A=576
The area of this square is 576cm2.
Hope this helps!
Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:
Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.
i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:
As time can't be negative hence we will consider:
Hence, grasshopper will land on the ground after 1.5 sec.
