It represents 1/2, 50% or half of the equation.
it’s also the numerator, tells how many pieces you have from the whole.
Answer:
a. sine
Step-by-step explanation:
As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.
In a right-angled triangle, there is a formula as following:
<em>+) sine (an acute angle) = (length of its opposite side)/ hypotenuse</em>
In the figure, angle B and length of the hypotenuse are given.
As x is the length of AC and AC is the opposite side to angle B
=> So that we can use sine to find x
Answer:
y = -1/2 is a horizontal line; a line with no slope. With that said, it is linear.
Step-by-step explanation:
Answer:
<h2>7. 62.8 sq.in.</h2><h2>8. 21.2 sq.in.</h2>
Step-by-step explanation:
The formula of an area of a triangle:
a, b - adjacent sides
θ - included angle
=============================================
7.
a = 9in, b = 14in, θ = 85°
sin85° ≈ 0.9962
Substitute:
8.
a = 12 in, b = 5 in, θ = 135°
sin135° = sin(180° - 45°) = sin45° ≈ 0.7071 <em>used sin(180° - x) = sin(x)</em>
Substitute:
