Answer:
m MN = 70°
Step-by-step explanation:
∠MLN is an angle formed by the chords ML and LN and is calculated as
∠MLN = 0.5( m arc MN ), that is
35° = 0.5 arc MN ( multiply both sides by 2 )
arc MN = 2 × 35° = 70°
Answer:
-50
Step-by-step explanation:
b-5 
b-5 = -45 ( collect like terms)
b = -45 + -5
b = -45 -5 b = -50
The temperature would be (21.5 + 6.25) which is 27.75
Answer:
(3x + 4)
Step-by-step explanation:
9x²+27x+20 can be factored out to (3x + 4)(3x + 5)
