Area of rectangle =wxl
A=(3x+5)(x-3)
A=3x^2+5x-15-9x
A=3x^2-4x-15
69,017,409 is the correct answer
Answer:
x = 62
Step-by-step explanation:
If the triangle has two values that are the same like your 6s that means that they have the same angle, so you take the angle(56 degrees) and subtract 180 and 56 making 124. You take 124 and divide it by 2. Making x =62.
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+ 
= 
, that is
1 + cot²θ = cosec²θ ← as required
Answer:
a = 1.8 cm
Step-by-step explanation:
Here. we want to find the value of a
To do this, we are going to use the sine rule
it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle
From the diagram, we have that;
The angle facing a is;
180-15-105 = 60
So, we have that
a/sin 60 = 2/sin 105
a = 2sin 60/sin 105
a = 1.794 cm
