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.
The sum of angles in a quadrilateral is 360°.
75° +125° +∠T +60° = 360°
∠T = 360° -260° = 100°

Hello from MrBillDoesMath!
Answer:
T(1) = 4
T(n) = T(n-1) + 18 , n > 1
Discussion:
Consecutive terms appear to increase by 18. This suggests the formula
T(1) = 4
T(n) = T(n-1) + 18 , n > 1
Thank you,
MrB
Answer:
2890 sq. meters
Step-by-step explanation:
The area of the whole garden is 85 x 50 = 4250 sq. meters. Since the flowers take up 32%, that means the grass must take up 100-32, or 68% of the garden. 68% of 4250 is 2890 sq. meters.
Hope this helped! :)
