Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10

<h3><em>Further explanation </em></h3>
The derivative magnitude is a quantity derived from the principal amount
7 main quantities have been determined based on international standards, namely:
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, ampere (A)
- 7. Amount of substance, mol (m)
Newton (N) is one unit of force (F) which is a quantity derived from mass (m), length (l) and time (s)
Newton can be expressed in terms of Kg m / s²
Formula used:
F = m. a
N = kg. m / s²
In the British system there are units of slug, feet, and pounds so that the unit of force becomes:
F = m. a
Lb = slug. ft / s²
The relationship between the two-unit systems above is:
1 kg = 0.0685 slug
1 slug = 14.59 kg
1 newton = 0.225 lb
1 lb = 4,448 newtons
1 ft = 0.3048 m
So if we change 15 N to lb by using slug and ft
15 N = 15 * (1 / 14.59) slug * (1 / 0.3048) ft / s²
15 N = 3,375 slug ft / s ²
15 N = 3,375 lb
or we convert directly:
15 N = 15 * 0.225 lb
15 N = 3,375 lb
