It would be 28+250% of 28 =98
X = 5; 2(5) - 1 = 9. 4(9) = 36
Area of triangle ABC = 80 square units
Step-by-step explanation:
We need to find the area of triangle ABC when we are given:
a= 15, b=12 and C=63°
We can find area of triangle using SAS (Side Angle Side)
The formula used is:
We are given a= 15, b=12 and C=63°, Putting values in the formula
Solving
So, Area = 80.19
Rounding off to nearest whole number:
Area = 80 square units

So, first set the two Y values equal to each other.
4x+9 = -1+8x
Add and subtract values to both sides making the x coordinates on one side:
4x = 10
Finally, divide.
x = 10/4 = 2.5
Answer and Step-by-step explanation:
These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.
They are functions revealing the shape of a right triangle.
Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.
Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.
