Answer:
Step-by-step explanation:
Call high street is a, using Pythagorean Theorem we have:
x^2 = 4 + a^2
b^2 = a^2 + 36
64 = x^2 + b^2
so we have x^2 = 16, a^2 = 12, b^2 = 48
so x= 4
The vertex is (-1,0). you can find this after putting the equation in standard form by completing the square.
2➗5 for a division problem and for a fraction it is 2/5
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°
