Answer:
Step-by-step explanation:
We can find the area of the triangle when two sides are given and the angle in between the two sides.
b and c are the sides and A is the angle in between b and c.
Answer: c. (1/2) bc sin A
<u>Step-by-step explanation:</u>
You can find the area of a triangle using trigonometry if you know the lengths of two sides and the measure of the included angle using the following formula:

y=8.94
Step-by-step explanation:
use the formula: a^2+b^2=c^2
64+y^2=144
y=
or y=8.94
The first and the third option are correct. if you fail to do the second and last they will take away your house lol
This is what I got hope it helps!
Using Sine. Sine = Opposite / Hypotenuse sin 60° = a / (6√3) But sin60° = √3/2 √3/2 = a/(6√3) Cross multiply 2*a = 6√3 * √3 2a = 6 * √(3*3) 2a = 6*3 a = 6*3/2 a = 3*3 = 9 Option E . Hope this helps.
Answer: 7
Step-by-step explanation:
They are alternate interior angle
2x + 5 = 3x -2
2x = 3x -7
-x = -7
x = 7
