Answer:
11
Step-by-step explanation:
Given:
Using PEDMAS rule to solve it.
Now, simplifying:
We first open parenthesis which is (-7) = -7
=
Now, we evaluate the exponent which is
Next, we divide -36 by 12 to get -3
=
Next, we multiply -2 and -7 to get 14
=
Lastly, we add -3 and 14 to get 11
=
∴ Answer is 11
Answer:
x = 28
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
Then x/(x +10) = 42/(42 +15)
x(57) = 42(x + 10)
57x = 42x + 420
15x = 420
x = 28

Answer:
? = 57
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos ? = adj/ hyp
cos ? = 14/26
Taking the inverse cos of each side
cos ^-1 ( cos ?) = cos ^-1 ( 14/26)
? = 57.42102961
To the nearest degree
? = 57
