Answer:
x=51
Step-by-step explanation:
There are two ways you can go about this
You can either say that the sum of interior angles in a triangle is equal to 180 so you do 180-39-90=51
Or you could use the exterior angle theorem, which means that 90=39+x, simplify that and you get that x=51
Answer:
its 210
Step-by-step explanation:
area of rect is 20×12=240
tri angle area=1/2×5×12=30
so 240-30=210
HOPE THIS HELPS!!

By definition a function can have only one value of y for any given value of x.
Since B. contains both (-1,2) and (-1,0), y has two values for the same value of x and thus B. cannot be a function...

Step-by-step explanation:
Answer:
9.2 ft
Step-by-step explanation:
The length of the ladder is 15 ft
The ladder makes an angle of 52° with the ground
The distance (x) from the base of the house to the foot of the ladder is given by;
= cos 52°
x = 15 × cos 52° = 9.23492213 ft
Which equals to 9.2 ft (rounded off to tenth of a foot)
