Answer:
19°
Step-by-step explanation:
Set up the equation (triangles add up to 180 degrees)(Right angles are 90 degrees).
39 + 90 + 2x + 13 = 180
142 + 2x = 180
2x = 38
x = 19

Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres
