The answer is B I agree with him/her
This is an isosceles triangle. The definition of an isosceles triangle is a triangle with at least two congruent sides and angles. If 2 angles on a triangle are congruent (in this case 45 and 45 are two congruent angles) then triangle is isosceles. Therefore the two sides of triangle will be congruent. We know that the triangle is a right triangle because it has a hypotenuse. If a triangle has a hypotenuse then it's a right triangle. We can apply the Pythagorean theorem: a^2 + b^2 = c^2
A and B are the legs and C is the hypotenuse.
We can plug C in the equation:
a^2 + b^2 = 128
What do we know about the legs of the isosceles triangle? They are congruent so a and b have to be equal. From here it's simply guess and check. Will 8 work?
8^2 + 8^2 = 128
64 + 64 = 128
128=128
Yes the value 8 works so the length of two legs of the triangle is 8.
<span>3x+9=5x+1
Subtract 3x from both sides
9=2x+1
Subtract 1 from both sides
8=2x
Divide 2 on both sides
Final Answer: 4=x</span>
Answer:
9 cm
Step-by-step explanation:
The formula to find the area of a square is Base times height (B x H)
Since a square has equal sides, it means each side is 3 centimeters.
So, all you have to do is 3 times 3.
3 x 3=9
<u>Final answer</u>
9 cm
22 and 23
