Answer:
Step-by-step explanation:
According to the diagram ,
Hypotenuse = 10√3
Opposite = x
Adjacent = y
α = 60
Using SOHCAHTOA ,
Sin α = opp / hyp
Sin 60= x/10√3
√3/2= x/10√3
x = 15
Pythagoras theorem ;
Hypotenuse ^2 = Opposite ^2 +Adjacent ^2
10√3 ^2 = 15^2+ y^2
300 = 225 +y ^2
300 -225 = y^2
75 = y^2
y = √75y
y = 5√3
Answer:
9 × 7 + (8 - 5) = 66
Step-by-step explanation:
9 × 7 + 8 - 5 = 66
Applying the order of operations (PEMDAS);
The parenthesis would go to 9 × 7 + (8 - 5) = 66
