Please help answer these questions. My teacher said they were really easy but I just don't understand. Will mark brainliest !!!
kodGreya [7K]

Answer:

1.  A = 59

2.  A = 43

Step-by-step explanation:

If we have a right triangle  we can use sin, cos and tan.

sin = opp/ hypotenuse

cos= adjacent/ hypotenuse

tan = opposite/ adjacent


For the first problem, we know the opposite and adjacent sides to angle A

tan A = opposite/ adjacent

tan A = 8.8 / 5.2

Take the inverse of each side

tan ^-1 tan A = tan ^-1 (8.8/5.2)

A = 59.42077313

To the nearest degree

A = 59 degrees


For the second problem, we know the  adjacent side and the hypotenuse to angle A

cos A = adjacent/hypotenuse

cos A = 15.3/21

Take the inverse of each side

cos ^-1 cos A = cos ^-1 (15.3/21)

A = 43.23323481

To the nearest degree

A = 43 degrees

Suppose y is a positive integer.If x-(-y)=z will z be greater than x ?
alexira [117]

Answer:

Yes, <em>z</em> will be greater than <em>x.</em>

Step-by-step explanation:

Given expression is x- (-y)=z \ for \ y \ is \ a \ positive \ integer.

now let <em>y = 2 </em>and <em>x = 1</em>

Then, x- (-y)=z \\1+2 = 3 \\\\

where z> x i.e. <em>3 > 1</em>

on simplifying the given  expression in terms of y

y=z-x

now suppose if <em>x = 7 and z=3 </em>then,

y = (z-x) = (3-7) = (-4)

which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then  z will be greater than x.
