Step-by-step explanation:
Given: The energy needed for 1 hour of running for an adult
Therefore. the energy needed for seven hours of running=
Since, he energy released by metabolism of 1 average candy bar
Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.=
Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.

Answer:
m∠ZWX = 105°
Step-by-step explanation:
Properties of a kite,
1). One diagonal of a kite bisects at least one pair of opposite angles.
2). Diagonals of a kite kite are perpendicular to each other.
In ΔWTZ,
m∠WZT =
=
= 50°
m∠WTZ = 90° [By second property]
m∠WZT + m∠WTZ + m∠ZWT = 180°
50° + 90° + m∠ZWT = 180°
m∠ZWT = 180° - 140°
= 40°
Similarly, in ΔWTX,
m(∠WXT) =
= 25°
m(∠WTX) = 90°
m∠WTX + m∠WXT + m∠TWX = 180°
90° + 25° + m∠TWX = 180°
m∠TWX = 180° - 115°
= 65°
Since, m∠ZWX = m∠ZWT + m∠TWX
Therefore, m∠ZWX = 40° + 65°
= 105°
