The length of PQ is 19.66 units
Step-by-step explanation:
The given is:
1. PK = KQ = 12
2. m∠P = 35º
We need to find the length pf PQ
∵ PK = KQ
∴ m∠P = m∠Q
∵ m∠P = 35°
∴ m∠Q = 35°
The sum of measures of the angles of a triangle is 180°
∴ m∠P + m∠Q + m∠K = 180°
∴ 35 + 35 + m∠K = 180
∴ 70 + m∠K = 180
- Subtract 70 from both sides
∴ m∠K = 110°
Let us use cosine rule to find the length of PQ
∵ PQ =
∵ PK = 12 , KQ = 12 , m∠K = 110°
- Substitute these values in the rule
∴ PQ =
∴ PQ = 19.66
The length of PQ is 19.66 units

Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
=
=
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
=

Answer:
y=-5/3x+20
Step-by-step explanation:
Let the equation of the required line be represented as
This line is perpendicular to the line
So the equation of the required line becomes
This line passes through the point (15.-5)
So the equation of the required line is
