Step-by-step explanation:
cos(-60°) = cos(60°) = ½
Answer: triangles are similar.
Step-by-step explanation:
Givn : OK = 3, OJ = 30, KN = 1, JM = 3#
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means
That means the three angles of triangle OKJ are equal to the corresponding three angles of triangle ONM.
Hence the to triangles are similar.
Maybe the answer is 1 x 3
Answer:
x<-5
Step-by-step explanation:
The area of the composite figure is
Explanation:
From the given figure, we can see that the area of the composite figure = area of the rectangle + area of the triangle.
Area of the rectangle :
The formula is given by
where and
Substituting, we have,
Thus, the area of the rectangle =
Area of the triangle :
The formula is given by
where
and
Substituting, we have,
Thus, the area of the triangle =
Area of the composite figure = Area of the rectangle + area of the triangle
Area of the composite figure =
Thus, the area of the composite figure is
