Answer:
x=8
Step-by-step explanation:
x^2+15^2=17^2, x=sqrt(64)=8
Answer:
Area of Square= 12*12= 144
Area of Circle= πr2
Radius= 12/2= 6
Area of Circle= 3.14*6*6 =113.04
Area of shaded region= 144- 113.04 = 30.96 = 31.0 (1 dp)
Answer:
d) √2/2
Step-by-step explanation:
cos∠E= 5/5√2= 1/√2=√2/2
Correct option is d)√2/2
Answer:
Step-by-step explanation:
We can add the same quantity to both sides of the equations, and still have an equivalent equation. Let's add to both sides, then sum like terms
(this is the rule that allows us to move items from one side do the other of the equal sign by changing its sign)
At this point we have a solution, let's replace it to verify
Answer:
a1, 4an, 2, 1
Step-by-step explanation:
