6x=18
1/5x=25
8+x=22
2/3x =12
4x+4=2x. 2x=-4
x+1/4x=150. Or 5/4x =150
3x-45=30
1/2x-14=x+2
Answer:
21/35
Step-by-step explanation:
Given :
- A right angled triangle with sides 28 , 35 ,21 .
And we need to find the value of cos A. We know that cosine is the ratio of base and Hypotenuse. So that ,
cos A = b/h
cosA = 21/35
- <u>Hence </u><u>the</u><u> </u><u>required</u><u> </u><u>Answer</u><u> </u><u>is </u><u>2</u><u>1</u><u>/</u><u>35</u><u>.</u>
Answer:
333
Step-by-step explanation:
The area of the square is 81 bc 9x9 = 81,
the formula for a triangle is base x height divided by 1/2
the base 9 x height 14 = 126 then divide by 1/2(or 2) to get 63, because all 4 triangles are congruent do 63 x 4 to get the answer of all 4 triangles which is 252.
Then add the area of the square to the area of the 4 triangles, 81 + 252 = 333
