Answer:
Height = 8 units
Step-by-step explanation:
Area of a triangle = square units
= square units
Height of the triangle = units
= units
Formula to calculate the area of a triangle is,
Area =
Height =
=
= 8 units
Therefore, height of the given triangle is 8 units.
The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)

C
