Answer:
-108
Step-by-step explanation:
-8 - ( -10 )²
= -8 - 100
= -108
Answer:
1 = 115°
2 = 115°
3 = 65°
Step-by-step explanation:
P=65, so S (3) =65
360-65-65=230
230/2=115
Q (1) = 115
R (2) = 115
Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
To solve 4n you need to divide both sides by 4
