Answer:
B) 1.4
Step-by-step explanation:
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.
sin(B)=opp/hyp
Plug in your numbers so the equation will turn out to be 3(4)+6/2(3) , you need to simplify 6/2 which will be 3 and 3 times 3 = 9 so the equation will be 3(4)+9 and 3 times 4 = 12 so the equation will now be 12+9 = 21
Answer= 21
Answer:
Martin has more cake than Sheena
Step-by-step explanation:
Chocolate Cake = 24 pieces
Vanilla Cake = 20 pieces
Martin: 3/24, 1/20
Sheena: 1/24, 2/20
Martin:
Step 1:
3/24 + 1/20
Step 2:
60/480 + 24/480 = 84/480
Sheena:
Step 1:
1/24 + 2/20
Step 2:
20/480 + 48/480 = 68/480
Martin has more cake than Sheena
Hope This Helps :)
In a triangle, the three interior angles always add to 180°
m∠1 = x+20
m∠2 = 2x+10
m∠3 = 4x-60
x+ 20 + 2x + 10 + 4x - 60 = 180
7x - 30 = 180
7x = 180 + 30
7x = 210
x = 210/7
x = 30
m∠1 = x+20 = 30 + 20 = 50°
m∠2 = 2x+10 = 2*30 + 10 = 70°
m∠3 = 4x-60 = 4 * 30 - 60 = 60°
