Answer:
Theta = 59 degrees
Step-by-step explanation:
Here, we want to get the value of the marked angle
To do this, we use the appropriate trigonometric ratio
From what we have,
The side 42 ft is adjacent the angle given
The side facing the right angle is 82 ft
The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse
Cos theta = 42/82
theta = cos^-1 0.5122
theta= 59.189
To the nearest degrees, this is 59 degrees
Answer:
-3
Step-by-step explanation:
First you subtract the first equation from the second one and you get:
3x + 3y = 3
x + y = 1
y = 1 - x
Then you use it on the first equation
888x + 889 (1 - x) = 890
888x + 889 - 889x = 890
-x = 1
x = -1
y = 1 - x
y = 1 - (-1) = 2
Now that you have those two numbers, we have to subtract the value of x from y:
x - y
-1 - 2 = -3
Hope this helps bro
Multiply 13 by the 2 above the divide line
13*2 = 26
so the number in the box should be 260
The surface area would be 16 square meters!
Is it 25? because 25 divided by 2 is 50
