Answer:

Angle A = 40.6°

Step-by-step explanation:

For any right angle triangle we know the Pythagoras theorem reveals

Hypotenuse² = Height²+Base²

By this formula we will calculate the length of Hypotenuse

H² = 6²+7²

⇒ H =√36+49 = √85 = 9.22

Now from the given triangle sin A = Height/ Hypotenuse

sin A = 6/9.22 = 0.651

Therefore $A = sin^{-1}(.651) = 40.6$

So angle A = 40.6°

Answer:

$y=-3.2\\\\y=-2.2\\\\y=-1.8$

Step-by-step explanation:

Insert the given x values for the given equation to find the corresponding y coordinate:

$y=0.2x-2$

$x:-6,-1,1$

Insert -6:

$y=0.2(-6)-2$

Simplify multiplication (when multiplying a negative and a positive, the result will always be negative):

$y=-1.2-2$

Simplify (when subtracting from a negative number, add the values, but keep the negative symbol):

$y=-3.2$

Insert -1:

$y=0.2(-1)-2\\\\y=-0.2-2\\\\y=-2.2$

Insert 1:

$y=0.2(1)-2\\\\y=0.2-2\\\\y=-1.8$

:Done

1) 2x11 = I don’t know how to do this

Fynjy0 [20]

Answer:

22, Twenty Two

Step-by-step explanation:

A good way to look at multiplying 11 is that the number, if it’s under 10, will then be two of that number. For instance, 4 x 11 = 44, 6 x 11 = 66, and so on and so forth.
