73.0
Step-by-step explanation:
tan 67°=O/A=h/31
h=31tan67°
h=73.0
Acute angle: measure between 0 degrees and 90 degrees
Right angle: measure is 90 degreas
Obtuse angle: measure between 90 degrees and 180 degrees
Straight angle: measure is 180 degrees
Answer:
4
Step-by-step explanation:
the formula for area of a rectangle is
Area = length x width
since both the length and the width of the rectangle lie on the same x and y axis, we can find the distance between the width and the distance between the length by subtracting
(-4,9) (-4,-3)
these points lie on the same x axis, so they create a vertical line
9-(-3) = 12
12 units is the distance between them
(-4,-3) (-1,-3)
these points lie on the same y axis, so they create a horizontal line
-1-(-4) = 3
3 units is the distance between them
now that we have the length and the width, we can find the area
A = 12 x 3
A = 36 units²
since you have the 75, we know that a would equal 105 for line g , since a line = 180 degrees
so to make line f parallel with g it needs the same angles with line n as line g has
so if a = 105, then angle d would also need to be 105
The answer is D
