Idk but I think you just add the ft and the height of H
Do 7777. Circle the 7 in the thousands place and underline the 7 in the ones place
Answer:
a). m∠a = 62°
b). m∠b = 118°
Step-by-step explanation:
a). Since, an angle inscribed in a semicircle is a right angle,
m∠ACB = 90°
By triangle sum theorem in ΔABC,
m∠CAB + m∠ACB + m∠ABC = 180°
28° + 90° + m∠ABC = 180°
118° + m∠ABC = 180°
m∠ABC = 180°- 118°
a = 62°
b). Since, quadrilateral ABCD is a cyclic quadrilateral,
m∠ADC + m∠ABC = 180°
b + a = 180°
b + 62° = 180°
b = 180° - 62°
b = 118°
The variable "y" equals the square root of two and the negative square root of two.
The problem may be solved using the quadratic formula.
4/5 seconds is 0.8 seconds as a fraction.
