Answer:
19.5 miles
Step-by-step explanation:
The question is represented in the image attached.
∠A = 45°, ∠B = 45° + (216° - 180°) = 81°
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
45° + 81° + ∠C = 180°
126 + ∠C = 180
∠C = 180 - 126
∠C = 54°
The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:
b = length of beginning of submarine to end point. Using sine rule:
Answer:
c
Step-by-step explanation:
X²+20-20=4-20
x²=-16
Take the square roots of each side: x=the square root of -16
You cannot do this so there is no solution
However, I'm not perfectly sure, so wait for other answers just in case
Answer:
10.7 cm^2
Step-by-step explanation:
First find the area of the base
A = 1/2 *2*1.7
A =1.7
Then find the area of one of the sides
A = 1/2 (2*3)
A = 3
There are 3 sides and they are identical
Multiply one of the sides by 3
3*3=9
Add the sides and the base together
9+1.7
10.7 cm^2
