Question

Find the value of x. Find m

Answer 1

Answer:

∠ QRS = 100°

Step-by-step explanation:

Since RU bisects ∠ QRS , then

∠ QRU = ∠ SRU , that is

$\frac{1}{2}$ x + 10 = 50 ( subtract 10 from both sides )

$\frac{1}{2}$ x = 40 ( multiply both sides by 2 )

x = 80

Then

∠ QRU = $\frac{1}{2}$ x + 10 = 0.5 × 80 + 10 = 40 + 10 = 50°

∠ QRS = 50° + 50° = 100°
