The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.
A=1/2(9)(4)
Multiply to get 18 square cm, which is choice D.
Answer:
V=10−3y
Step-by-step explanation:
Solve for V by simplifying both sides of the equation, then isolating the variable.
With these values x = 14.
In order to find this, we must note that LM will be half of KM (since L is the midpoint). Because we know this, we also know that we can multiply LM by 2 and set equal to KM.
2LM = KM
2(2x + 4) = 5x - 6
4x + 8 = 5x - 6
8 = x - 6
14 = x
Answer: a. (2.5, 300°) and (-2.5, 120°)
b. (4, 270°) and (-4, 90°)
<u>Step-by-step explanation:</u>
Polar coordinates are written as (r, θ) where
- r is the radius
- θ is the angle
In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)
You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)
↓
(300 - 180)
In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)
You can also list the radius as -4 at angle 90° --> (-4, 90°)
↓
(270 - 180)
Answer:
49.69
Step-by-step explanation:
use Equation for cos15°
cos15°=48y/distance
0.9659=48/Distance
distance=48/0.96592
distance=49.69 yard
