<u>Answer:</u>
x = 5.67
<u>Step-by-step explanation:</u>
We are given a right angled triangle with a length of the hypotenuse 8 with the remaining two sides (base and perpendicular) that are equal to each other.
Assuming the two equal legs of this right angled triangle to be x, we can use the Pythagoras Theorem to find the value of x.
Taking square root at both the sides to get:
Therefore, x = 5.67.
The sum of the angles <6 and <3 must be 180. Since <3 and <1 are opposed to the top, their measure are equal. We need then to calculate the measure of angle >3 = 180 - <6 = 180-85=95
m(<1) = 95
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
The answer is already in its simplest form. You can not add the two because the have different variables. Hope this helps ;)))
