Answer:
Step-by-step explanation:
a°=180°-36°=144° b°=180°-113°=67°
a°=144° and b°=67°
144+67=211
36+113=149
149+211=360
Answer:
rice --- no of people
1 ---- 3
2 ---- 6
4 ---- 12
12 --- 36
43 --- 129
Step-by-step explanation:
This is in direct proportion. The constant value of it is 3 so you have to multiply the number of cups into three to get the number of people it can feed
The smallest number that has 1 2 3 4 5 as factors is: 3x4x5 = 60
The special name is Least Common Multiple, because 60 is the LCM of 1, 2, 3, 4, and 5
Let a =70° and b= 10° (and a-b=70-10 =60)
We have the following trigonometric identity:
sin(a-b) = sin(a).cos(b)-sin(b).cos(a) OR:
sin(70-10) = sin70.cos10 - sin10.cos70
But sin(70-10) = sin(60) and we know that sin(60°) =(√3)/2
