Answer:
Step-by-step explanation:
Angle A = 90°
Angle B = 45°
According to the angle sum property
Angle A + Angle B + Angle C = 180°
90° + 45° + Angle C = 180°
Angle C = 45°
As the two angles are equal so the triangle is right angle isosceles triangle.
Answer:
(-1)/2
Step-by-step explanation:
Evaluate u + a t where u = 2, a = -5 and t = 1/2:
u + a t = 2 - 5/2
Put 2 - 5/2 over the common denominator 2. 2 - 5/2 = (2×2)/2 - 5/2:
(2×2)/2 - 5/2
2×2 = 4:
4/2 - 5/2
4/2 - 5/2 = (4 - 5)/2:
(4 - 5)/2
4 - 5 = -1:
Answer: (-1)/2
