Answer:
Step-by-step explanation: d
Answer: 12 units squared
Explanation:
A=1/2 bh
A=1/2 8*3
A=1/2 24
A=12
Therefore, the area of this triangle is 12 units squared
Answer:
So the sum of a triangle is 180° so 45°+27°= 72°
180° - 72°= 108°
X = 108°
Answer:
r+7
Step-by-step explanation:
Answer:
sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5
Step-by-step explanation:
We need to find sine, cosine, and tangent of theta for this triangle.
First, define the different trigonometric functions:
- sine is opposite side to the angle divided by the hypotenuse (longest side not adjacent to the 90 degree angle)
- cosine is the adjacent side next to the angle divided by the hypotenuse
- tangent is the opposite side to the angle divided by the adjacent side
Now, look at theta (θ):
- the opposite side is marked 12
- the adjacent side is marked 5
- the hypotenuse is marked 13
So:
- sin(θ) = opposite / hypotenuse = 12/13
- cos(θ) = adjacent / hypotenuse = 5/13
- tan(θ) = opposite / adjacent = 12/5
Thus the answers are: sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5.
